Gun barrel
–
A gun barrel is a part of firearms and artillery pieces. The hollow interior of the barrel is called the bore, a gun barrel must be able to hold in the expanding gas produced by the propellants to ensure that optimum muzzle velocity is attained by the projectile as it is being pushed out by the expanding gas. Modern small arms barrels are made of known and tested to withstand the pressures involved. Artillery pieces are made by various techniques providing reliably sufficient strength, early firearms were muzzle-loading, with powder, and then shot loaded from the muzzle, capable of only a low rate of fire. During the 19th century effective mechanical locks were invented that sealed a breech-loading weapon against the escape of propellant gases, the early Chinese, the inventors of gunpowder, used bamboo, a naturally tubular stalk, as the first barrels in gunpowder projectile weapons. Early European guns were made of iron, usually with several strengthening bands of the metal wrapped around circular wrought iron rings. The Chinese were the first to master cast-iron cannon barrels, early cannon barrels were very thick for their caliber.

Cartridge (firearms)
–
Military and commercial producers continue to pursue the goal of caseless ammunition. A cartridge without a bullet is called a blank, One that is completely inert is called a dummy. Some artillery ammunition uses the same concept as found in small arms. In other cases, the shell is separate from the propellant charge. In popular use, the bullet is often misused to refer to a complete cartridge. The cartridge case seals a firing chamber in all directions excepting the bore, a firing pin strikes the primer and ignites it. The primer compound deflagrates, it does not detonate, a jet of burning gas from the primer ignites the propellant. Gases from the burning powder pressurize and expand the case to seal it against the chamber wall and these propellant gases push on the bullet base. In response to pressure, the bullet will move in the path of least resistance which is down the bore of the barrel. After the bullet leaves the barrel, the pressure drops to atmospheric pressure. The case, which had been expanded by chamber pressure. This eases removal of the case from the chamber, brass is a commonly used case material because it is resistant to corrosion. A brass case head can be work-hardened to withstand the pressures of cartridges. The neck and body portion of a case is easily annealed to make the case ductile enough to allow reforming so that it can be reloaded many times. Steel is used in some plinking ammunition, as well as in military ammunition. Steel is less expensive than brass, but it is not feasible to reload, Military forces typically consider small arms cartridge cases to be disposable, one-time-use devices. However, case weight affects how much ammunition a soldier can carry, conversely, steel is more susceptible to contamination and damage so all such cases are varnished or otherwise sealed against the elements. One downside caused by the strength of steel in the neck of these cases is that propellant gas can blow back past the neck

.40 S&W
–
The.40 S&W is a rimless pistol cartridge developed jointly by major American firearms manufacturers Smith & Wesson and Winchester. It uses 0. 40-inch diameter bullets ranging in weight from 105 to 200 grains, the semi-automatic pistol offered two advantages over the revolver, 1) increased ammunition capacity and 2) increased ease of reloading during a firefight. The FBI was satisfied with the performance of its.38 Special +P158 gr L. S. W. C. H. P, cartridge based on decades of dependable performance. Ammunition for the new semi-automatic pistol had to deliver terminal performance equal or superior to the.38 Special FBI Load, during tests of the 9×19mm and. During this collaboration with the FBI, S&W realized that downsizing the 10mm full power to meet the FBI medium velocity specification meant less powder, S&W then teamed with Winchester to produce a new cartridge, the.40 S&W. It uses a small pistol primer whereas the 10mm cartridge uses a large pistol primer, the.40 S&W cartridge debuted January 17,1990, along with the new Smith & Wesson Model 4006 pistol, although it was several months before the pistols were available for purchase. Beat Smith & Wesson to the shelves in 1990, with pistols chambered in.40 S&W which were announced a week before the 4006. Glocks rapid introduction was aided by its engineering of a pistol chambered in 10mm Auto, since the.40 S&W uses the same bore diameter and case head as the 10mm Auto, it was merely a matter of adapting the 10mm design to the shorter 9×19mm Parabellum frames. The new guns and ammunition were an immediate success, the.40 S&W case length and overall cartridge length are shortened, but other dimensions except case web and wall thickness remain identical to the 10mm Auto. Both cartridges headspace on the mouth of the case, thus in a semi-auto they are not interchangeable. Fired from a 10mm semi-auto, the.40 Smith & Wesson cartridge will headspace on the extractor, if the cartridge is not held by the extractor, the chances for a ruptured primer are great. Smith & Wesson does make a double-action revolver that can fire either at will using moon clips, a single-action revolver in the. 38–40 chambering can also be modified to fire the.40 or the 10mm if it has an extra cylinder. Some.40 caliber handguns can be converted to 9mm with a purpose made barrel, magazine change. The.40 S&W has 1.25 ml cartridge case capacity. The common rifling twist rate for this cartridge is 406 millimetres,6 grooves, ∅ lands =9.91, mm, ∅ grooves =10.17 mm, land width =3.05 mm and the primer type is small pistol. Guidelines, the.40 S&W case can handle up to 225 megapascals piezo pressure, in C. I. P. -regulated countries every pistol/cartridge combo has to be proofed at 130% of this maximum C. I. P. pressure to certify for sale to consumers. The SAAMI pressure limit for the.40 S&W is set at 241.32 megapascals piezo pressure, the.40 S&W cartridge has been popular with law enforcement agencies in the United States, Canada, and Australia. Marshall & Sanow contend that with good jacketed hollow point bullets, apart from the imperfect relationship between ordnance gelatin ballistics and actual stopping power, critics pointed to the reduced power of the round compared with the 10mm Auto it was based on

Action (firearms)
–
In firearms terminology, an action is the mechanism that handles the ammunition or the method by which that mechanism works. Breech-loading weapons have actions, actions are not present on muzzleloaders. The mechanism that fires a muzzle-loader is called the lock, actions can be categorized in several ways, including single action versus double action, break action versus bolt action, and others. The term action can also short, long, and magnum if it is in reference to the length of the rifle’s receiver. The short action rifle usually can accommodate a cartridge length of 2.8 in or smaller, the long action rifle can accommodate a cartridge of 3.34 in, and the magnum action rifle can accommodate cartridges of 3.6 in, or longer in length. Manual operation is a term describing any type of firearm action that is loaded one shot at a time by the user rather than automatically. For example, break action is a form of operation using a simple hinge mechanism that is manually unlatched by the operator. These are actions wherein the breechblock lowers or drops into the receiver to open the breech, there are two principal types of dropping block, the tilting block and the falling block. In a tilting or pivoting block action, the breechblock is hinged on a pin mounted at the rear, when the lever is operated, the block tilts down and forward, exposing the chamber. The best-known pivoting block designs are the Peabody, the Peabody–Martini, the original Peabody rifles, manufactured by the Providence Tool Company, used a manually cocked side-hammer. The 1871 Martini–Henry which replaced the trapdoor Snider–Enfield was the standard British Army rifle of the later Victorian era, charles H. Ballards self-cocking tilting-block action was produced by the Marlin Firearms Company from 1875, and earned a superlative reputation among long-range Creedmoor target shooters. Surviving Marlin Ballards are today highly prized by collectors, especially those mounted in the elaborate Swiss-style Schützen stocks of the day. A falling-block action is a firearm action in which a solid metal breechblock slides vertically in grooves cut into the breech of the weapon. Examples of firearms using the falling block action are the Sharps rifle, in a rolling block action the breechblock takes the form of a part-cylinder, with a pivot pin through its axis. The operator rotates or rolls the block to open and close the breech, it is a simple, rugged, a break action is a type of firearm where the barrel are hinged and can be broken open to expose the breech. The earliest metallic-cartridge breechloaders designed for military issue began as conversions of muzzle-loading rifle-muskets. The upper rear portion of the barrel was filed or milled away, an internal angled firing pin allowed the re-use of the rifles existing side-hammer. The Allin action made by Springfield Arsenal in the US hinged forward, france countered in 1866 with its superior Chassepot rifle, also a paper-cartridge bolt action

Magazine (firearms)
–
A magazine is an ammunition storage and feeding device within or attached to a repeating firearm. Magazines can be removable or integral to the firearm, the magazine functions by moving the cartridges stored in the magazine into a position where they may be loaded into the chamber by the action of the firearm. The detachable magazine is often referred to as a clip, although this is technically inaccurate, magazines come in many shapes and sizes, from those of bolt-action express rifles that hold only a few rounds to drum magazines for self-loading rifles that can hold one hundred rounds or more. Various jurisdictions ban what they define as high-capacity magazines, with the increased use of semi-automatic and automatic firearms, the detachable box magazine became increasingly common. Soon after the adoption of the M1911 pistol, the magazine was settled on by the military and firearms experts. The defining difference between clips and magazines is the presence of a mechanism in a magazine, typically a spring-loaded follower. Use of the clip to refer to detachable magazines is a point of strong disagreement. The first mass-produced repeater was the Volcanic Rifle which used a bullet with the base filled with powder and primer fed into the chamber from a spring-loaded tube called a magazine. It was named after a building or room used to store ammunition, the anemic power of the Rocket Ball ammunition used in the Volcanic doomed it to limited popularity. The Henry repeating rifle is a lever-action, breech-loading, tubular magazine fed rifle, designed by Benjamin Tyler Henry in 1860, it was one of the first firearms to use self-contained metallic cartridges. The Henry was introduced in the early 1860s and produced through 1866 in the United States by the New Haven Arms Company and it was adopted in small quantities by the Union in the Civil War and favored for its greater firepower than the standard issue carbine. Many later found their way West and was famed both for its use at the Battle of the Little Bighorn, and being the basis for the iconic Winchester rifle which are made to this day. The Henry and Winchester rifles would go on to see service with a number of militaries including Turkey, switzerland and Italy adopted similar designs. The first magazine-fed firearm to achieve success was the Spencer repeating rifle. The Spencer used a magazine located in the butt of the gun instead of under the barrel. The Spencer was successful, but the rimfire ammunition did occasionally ignite in the magazine tube and it could also injure the user. The new bolt-action rifles began to favor with militaries in the 1880s and were often equipped with tubular magazines. The Mauser Model 1871 was originally a single-shot action that added a magazine in its 1884 update

Semi-automatic pistol
–
One cartridge is fired each time the trigger of a semi-automatic pistol is pulled, the pistols disconnector ensures this behavior. Additional terms sometimes used as synonyms for a semi-automatic pistol are automatic pistol, self-loading pistol, autopistol, a semi-automatic pistol harnesses the energy of one shot to reload the chamber for the next. After a round is fired, the spent casing is ejected, most pistols use recoil operation to do this, but some pistols use blowback or gas operation. Most types of semi-automatic pistols rely on a magazine to store ammunition before it is fired. Typically, the first round is loaded into the chamber by pulling back. This is called racking the slide or racking the gun, after the trigger is pulled and the round is fired, the recoil operation of the handgun automatically extracts and ejects the shell casing and reloads the chamber. This mode of operation allows for faster reloading and storing a larger number of cartridges than a revolver. Each pull of the trigger on a DAO semi-automatic pistol requires the amount of pressure. The Kel-Tec P-32 is an example of a DAO action, DAO semi-automatic pistols are most generally recommended only in the smaller, self-defense, concealable pistols, rather than in target or hunting pistols. A notable exception is Glock-brand pistols which optimize preset triggers, and this allows for significantly shorter trigger pulls than DAO. The trigger spring can be replaced with a one and paired with a low-strength sear connector resulting in lightened trigger pulls to improve a shooters accuracy. Standard modern semi-automatic pistols are double action, also sometimes known as double-action/single-action. In this design, the hammer or striker may be either thumb-cocked or activated by pulling the trigger when firing the first shot, the hammer or striker is recocked automatically during each firing cycle. In double-action pistols, the first pull of the trigger requires roughly twice as much pressure as subsequent firings, the Beretta 92F/FS, a full-sized, service, semi-automatic pistol is an example of this style of action. A common mode of carry for DA semi-automatic pistols is with the full, a round chambered. In contrast, a single-action semi-automatic pistol must be cocked by first operating the slide or bolt, or, if a round is already chambered, the famed Colt M1911 is an example of this style of action. All SA semi-automatic pistols exhibit this feature, and automatically cock the hammer when the slide is first racked to chamber a round, a round can also be manually inserted in the chamber with the slide locked back. Then the safety can be applied, the normal mode of carrying an SA semi-automatic pistol is condition 1, popularly known as cocked and locked

Smith & Wesson
–
Smith & Wesson is a manufacturer of firearms in the United States. The corporate headquarters are based in Springfield, Massachusetts, founded in 1852, Smith & Wessons pistols and revolvers have become standard issue to police and armed forces throughout the world, in addition to their popularity among sport shooters. Apart from firearms, Smith & Wesson has been known for the types of ammunition it has introduced over the years. Wesson founded the Smith & Wesson Company in Norwich, Connecticut in 1852 to develop the Volcanic rifle, Smith developed a new Volcanic Cartridge, which he patented in 1854. The Smith & Wesson Company was renamed Volcanic Repeating Arms in 1855, Smith left the company and returned to his native Springfield, Massachusetts, Wesson stayed on as plant manager with Volcanic Repeating Arms. As Samuel Colts patent on the revolver was set to expire in 1856 and his research pointed out that a former Colt employee named Rollin White held the patent for a Bored-through cylinder, a component he would need for his invention. Wesson reconnected with Smith and the two partners approached White to manufacture a newly designed revolver-and-cartridge combination, rather than make White a partner in their company, Smith and Wesson paid him a royalty of $0.25 on every revolver that they made. It would become Whites responsibility to defend his patent in any court cases which led to his financial ruin. The orders for the Smith & Wesson Model 1 revolver outpaced the production capabilities. In 1860 demand was so great that Smith & Wesson expanded into a new facility, at the same time, the companys design was being infringed upon by other manufacturers which led to numerous lawsuits filed by Rollin White. In many of these part of the restitution came in the form of the offender being forced to stamp Manufactured for Smith & Wesson on the revolvers in question. Whites vigorous defense of his patent caused a problem for armsmakers in the United States at the time as they could not manufacture cartridge revolvers, at the end of the war the US Government charged White with causing the retardation of arms development in America. Demand for revolvers declined at the close of the Civil War, in 1870 the company introduced a large frame revolver in heavier calibers than the pocket sized revolvers it had been making. The design was known as the Smith & Wesson Model 3, after an organized campaign by the NRA and NSSF, thousands of retailers and tens of thousands of firearms consumers boycotted Smith & Wesson. On 11 May 2001, Saf-T-Hammer Corporation acquired Smith & Wesson Corp. from Tomkins plc for US$15 million, Saf-T-Hammer assumed US$30 million in debt, bringing the total purchase price to US$45 million. The acquisition of Smith & Wesson was chiefly brokered by Saf-T-Hammer President Bob Scott, after the purchase, Scott became the president of Smith & Wesson to guide the 157-year-old company back to its former standing in the market. On 15 February 2002, the name of the newly formed entity was changed to Smith & Wesson Holding Corporation, about 2006 Smith & Wesson refocused its marketing on big box retailers, according to Smith & Wesson CEO Mike Golden in a 2008 conference call with investors. In December 2014, Smith & Wesson Holding announced it was paying $130.5 million for Battenfeld Technologies, the company made the acquisition with the eventual intent to merge all its existing Smith & Wesson, M&P and Thompson Center Arms accessories into a single division

Safety (firearms)
–
In firearms, a safety or safety catch is a mechanism used to help prevent the accidental discharge of a firearm, helping to ensure safer handling. Safeties can generally be divided into such as internal safeties. Sometimes these are called passive and active safeties, respectively, some firearms manufactured after the late 1990s include mandatory integral locking mechanisms that must be deactivated by a unique key before the gun can be fired. These integral locking mechanisms are intended as child-safety devices during unattended storage of the firearm—not as safety mechanisms while carrying, other devices in this category are trigger locks, bore locks, and gun safes. The most common form of safety mechanism is a switch, button or lever that, other designs may block the hammer or striker from forward movement or act as a block to prevent them from contacting the firing pin. The M1911 design is an example of a handgun with a grip safety. The Uzi submachine gun is another example of a firearm with a grip safety, a related grip-type safety is the decocking grip found on some H&K pistols like the P7 Series. The firearm is cocked and ready to fire only when the front of the grip is squeezed by the operator. When the grip is released, the firearm is decocked, and the trigger will not cock the firearm, therefore it will not fire unless the grip is squeezed. Alternatively, the trigger can first be pulled and then it will fire when the grip is subsequently squeezed, finally, if both the grip is squeezed and the trigger pulled simultaneously, the pistol will fire. Another, unusual variant was found in the Ortgies semi-automatic pistols, to disengage the safety, a user would squeeze a lever until flush with the rear of the grip. Thus, engaging the safety also relieved some tension in the striker spring, as the Ortgies is a pocket pistol meant for personal defense, this feature eliminates the problem of failing to disengage the safety when one needs to shoot. Gripping the pistol tightly is all it takes to disengage the safety, most traditional semi-automatic double-action/single action pistols are designed to be carried with the hammer down on a chambered round, with or without a manual safety engaged. However, the act of cycling the action on such a firearm will leave the hammer cocked in single-action mode. To return the pistol to its state, it is necessary to uncock the hammer, usually by holding the hammer spur, carefully pulling the trigger. A decock/safety is a manual safety switch and decocking lever. A simpler two-way system was popularized by the Walther PP and is commonly seen on the Beretta 92. The SIG Sauer line of pistols, such as the SIG P226, the earliest use of a single-action decocker was the Vis wz.35 Radom redesign in 1932 to enable horsemen to safely holster their firearm with one hand

Browning Hi-Power
–
The Browning Hi Power is a single-action, semi-automatic handgun available in 9mm and.40 S&W calibers. It is based on a design by American firearms inventor John Browning, Browning died in 1926, several years before the design was finalized. The Hi-Power is one of the most widely used military pistols in history, the Hi Power name alludes to the 13-round magazine capacity, almost twice that of contemporary designs such as the Luger or Colt M1911. The pistol is often referred to as an HP or as a GP, the terms P-35 and HP-35 are also used, based on the introduction of the pistol in 1935. It is most often called the Hi Power, even in Belgium, other names include BAP, particularly in Irish Army service, or BHP. The Browning Hi-Power was designed in response to a French military requirement for a new service pistol and it was to accomplish all of this at a weight not exceeding 1 kg. FN commissioned John Browning to design a new military sidearm conforming to this specification, Browning built two different prototypes for the project in Utah and filed the patent for this pistol in the United States on June 28,1923, granted on February 22,1927. One was a blowback design, while the other was operated with a locked-breech recoil system. Both prototypes utilized the new staggered magazine design to increase capacity without increasing the pistols grip size or magazine length. The locked breech design was selected for development and testing. This model was striker-fired, and featured a magazine that held 16 rounds. The design was refined through several trials held by the Versailles Trial Commission and this version featured the removable barrel bushing and take down sequence of the Colt 1911. By 1931, the Browning Hi-Power design incorporated a shortened 13-round magazine, a curved rear grip strap, by 1934, the Hi-Power design was complete and ready to be produced. It was first adopted by Belgium for military service in 1935 as the Browning P-35, ultimately, France decided not to adopt the pistol, instead selecting the conceptually similar but lower-capacity Modèle 1935 pistol. The HP35 originally had a rounded, serrated hammer with a hole through it and this lighter hammer was harder to cock and had difficulty firing the harder Berdan-primed centerfire cartridges commonly used in Europe, often requiring a tightening of the hammer spring. This was replaced in 1972 by a hammer on both civilian and military models. However, the Browning Challenger and special variants of the Browning pistol still use the classic ring hammer, the Browning Hi-Power has undergone continuous refinement by FN since its introduction. The adjustable sights are available on commercial versions of the Hi-Power

California Highway Patrol
–
The California Highway Patrol is a law enforcement agency of the U. S. state of California. The CHP has patrol jurisdiction over all California highways and can act as the state police. It was reestablished as a department by Governor Earl Warren in 1947. The CHP gradually assumed increased responsibility beyond the enforcement of the State Vehicle Act and it is currently organized as part of the California State Transportation Agency. In addition to its patrol duties, the CHP also provides other services including protecting state buildings and facilities. The CHP also works with law enforcement agencies, providing assistance in investigations, patrol. The California Highway Patrol is the largest state agency in the United States, with more than 10,500 employees,7,200 of whom are sworn officers. The agency has jurisdiction over all California state routes, U. S. Highways, Interstate Highways. While the agencys mission is related to transportation, it also possesses full law enforcement authority. Furthermore, CHP officers act as bailiffs for the California Supreme Court and California Court of Appeal, CHP officers enforce the California Vehicle Code, pursue fugitives spotted on the highways, and attend to all significant obstructions and accidents within their jurisdiction. Beginning in 2013, the CHP switched to the Ford Explorer-based Ford Police Interceptor Utility fleet vehicles because the Ford Crown Victoria Police Interceptor was being phased out of production. CHP officers are responsible for investigating and disposing of car accidents, disabled vehicles, debris and they are often the first responders at the scene of an accident, and in turn summon paramedics, firefighters, tow truck drivers or Caltrans personnel. The CHP files traffic collision reports for state highways and within unincorporated areas, the CHP responds to and investigates all accidents involving school buses throughout the state including incorporated cities. CHP also has Multidisciplinary Accident Investigation Teams for the investigation of traffic collisions, the CHP also publishes data on traffic accidents in California from a database called SWITRS. After the September 11,2001 attacks the CHP became responsible for securing and patrolling a number of potential terrorist targets in California and these sites include nuclear power plants, government buildings, and key infrastructure sites. The CHP also maintains a SWAT team on 24‑hour stand‑by to respond to any terrorist activity, in September 2005, the CHP sent its two Mobile Field Forces to the Gulf Coast to assist in the aftermath of Hurricane Katrina. CHP investigators also work closely with agents of the State Bureau of Investigation, additionally, the CHP has dozens of narcotic patrol and explosive detection K‑9 teams stationed throughout the state. One of the California Highway Patrols additional responsibilities includes a governor protection detail, average officer pay was $118,000 in 2014

Colorado State Patrol
–
The CSP primarily enforces traffic laws on interstates and state highways, guards the state capitol and the Governor of Colorado, and has statewide general law enforcement jurisdiction. Founded in 1935 with only 44 men, it was one of four law enforcement agencies serving in Colorado at the time. Since two-way radios werent installed until 1949, officers usually received calls by visiting local gas stations, after dispatchers telephoned the station, the attendant would then place a red flag along the roadway, which would alert the officers to the call. The patrol was met with opposition from the public when it was formed, as well as other law enforcement agencies. This became the motto of the Colorado State Patrol, until the switch to auto-loading semi-automatic pistols, The CSP carried blue-steel,4 inch barreled Colt Python revolvers. CSP troopers now carry the Smith & Wesson M&P.40, additionally, all troopers are issued a Remington 870 shotgun and are given the option to carry either a department or personally owned M14 or AR-15 select-fire rifle. All CSP troopers are issued an ASP baton and OC, with Tasers started being used in 2011, in 2009, after many years of using Ford Crown Victoria patrol cars, the CSP began to introduce Dodge Chargers into its fleet. The CSP also uses Chevrolet Tahoes, Ford Police Interceptors and Chevrolet Caprices, the Hazardous Materials and Motor Carrier Safety sections use Ford F-150 trucks. Specific duties include, Enforcing all the laws of the state of Colorado on approximately 8,483 miles of state highways, investigating and report traffic crashes occurring on public property. Directing, controlling and regulating motor vehicle traffic on public roadways, inspecting vehicles for safety-related equipment violations. Inspecting vehicles carrying livestock for brand inspection certificates, providing community education and administer safety programs to the public. Regulating road closures for special events, inclement weather, or when necessary to prevent further injury or damage following an emergency, promulgating and enforcing rules and regulations for commercial motor vehicles. Operating a statewide law enforcement telecommunications system, performing criminal interdiction on Colorado highways, focusing on the transport of illegal drugs. Assisting in state homeland security efforts, providing emergency assistance in the event of major disasters, civil protests, or when requested by local law enforcement. A community program designed to impact the future of traffic safety and its emphasis is to identify and eliminate at-risk driving behavior.

Smith & Wesson M&P
–
The Smith & Wesson M&P is a polymer-framed, short recoil operated, locked breech semi-automatic pistol introduced in the summer of 2005 by the American company Smith & Wesson. It uses a Browning-type locking system, while targeted at law enforcement agencies, the M&P is also widely available on the commercial market. The M&P is an evolution of the Smith & Wesson Sigma and Smith & Wesson SW99 design. The M&P design has a trigger and enhanced ergonomics that allow for end-user customization. An industry standard picatinny rail and a higher grip has been afforded with an improved grip, many of the ergonomic study elements that had been incorporated into the Sigma and the Smith & Wesson SW99 were brought over to the M&P. The improved trigger weight and feel and the unique takedown method were meant to set the M&P apart from the popular Glock pistols, the M&P is a striker-fired semi-automatic pistol. This trigger system prevents the firearm from discharging unless the trigger is fully depressed, an internal lock and/or magazine disconnect are available as options and an optional external thumb safety became available in 2009. The pistol frame is made out of Zytel polymer reinforced with a steel chassis. The pistol comes with three removable and interchangeable grips, the slide and barrel are made out of stainless steel that after hardening is treated with a proprietary nitriding process called Melonite. The Melonite process produces a matte gray non-glare surface with a 68 Rockwell C surface hardness rating, the slide has four contact points with the frame. This was done to make the rail system self cleaning, by leaving room for any dirt or small objects to fall out of the weapon. As the slide of the pistol enters battery, the striker engages the sear, at this point, the sear is held back in a partially cocked condition. When the trigger of the M&P is pulled, the bar first engages the firing pin safety plunger, lifting it upward. At the rearward extreme of the trigger travel, it engages the sear. The sear is rotated downward by the bar, fully cocking. The striker makes contact with the primer of the chambered round, according to renowned M&P gunsmith Dan Burwell, the angle on the rear face of the sear creates a camming action against the striker. This camming action moves the striker to the rear very slightly during the trigger pull and this system is similar to the partially tensioned striker found in the Glock series of pistols. When the pistol cycles for the shot, the striker will be automatically pre-set in a 98% cocked position

Atlanta Police Department
–
The Atlanta Police Department is the law enforcement agency of the city of Atlanta, Georgia, U. S. The city shifted from its rural-based Marshal and Deputy Marshal model at the end of the 19th century, in 1873, the department was formed with 26 officers. Thomas Jones was elected the first Atlanta Chief of Police by the city council, the 1, 900+ officer force is led by Chief of Police Erika Shields. In 2012, at the urging of Atlanta Mayor Kasim Reed, on October 25,2013, it was announced that the Atlanta Police Department had 2,000 sworn officers. Prosecutors alleged that the officers falsified information and documents after the killing to justify the serving of the warrant, on April 26,2007, two officers pleaded guilty to manslaughter, violation of oath, criminal solicitation, and making false statements. One additionally pleaded guilty to perjury, on July 8,2011, it was reported in the Atlanta Journal Constitution that six police officers were fired for lying about events concerning a raid on the Atlanta Eagle Bar. In June 2011, a 343-page report was released that details how 16 officers lied or destroyed evidence when asked about the raid on the Eagle Bar. At least two of the officers in question had been cited for lying on another occasion in a drug case in October 2009. On April 8,2011, APD officers shot a 64-year-old U. S. Marine veteran who had fired shots at the ground in front of a man who was stealing from him. Vehicles, Ford Police Interceptor equipped with state-of-the-art Whelen LED Lighting packages, due to heavy wear and tear only all wheel drive or rear wheel drive vehicles are considered. In fall 2013, the Atlanta Police Department began phasing 70 new Ford Taurus Police interceptors into its fleet to replace the old Crown Victoria interceptors, the entire fleet totals around 300 vehicles and the remaining Crown Victoria interceptors will be phased out as they lose usefulness. The remaining 230 Crown Victoria interceptors will be replaced by Taurus interceptors over time, communications, Motorola Digital 800 MHz Trunking system that is one of the largest in the country and utilizes 24 channels. This system provides voice and data communications for the Atlanta Police, Fire, Watershed, Corrections, weapons, Smith & Wesson M&P.40 S&W. In July 2013 Glock secured a contract with the Atlanta Police Department for an order of 2300 full size Glock 22 Generation 4s to replace the Smith & Wesson M&P.40 and this breaks a 70+ year relationship between Smith & Wesson and the APD. The Glock 22 is being phased into service within the department over time, the Glock 22 is chambered in the.40 caliber Smith & Wesson round like the M&P that it replaces. APD SWAT adopted the full size Glock 21 Gen 4 due to requirements that favor the.45 ACP round over the.40 S&W round. In the City of Atlanta, there are six patrol zones which lie under the jurisdiction of the Field Operations Division of the Atlanta Police Department, Zone 1 covers the citys northwest side, west of Downtown Atlanta and north of I-20. Zone 2 covers all of the northern area

The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker

Revolver
–
A revolver is a repeating handgun that has a revolving cylinder containing multiple chambers and at least one barrel for firing. Revolvers might be regarded as a subset of pistols, or as a subset of handguns. Though the term revolver usually only refers to handguns, other firearms may also have a revolving chamber and these include some models of grenade launchers, shotguns, and rifles. Most revolvers contain five or six rounds in the cylinder, though the original name was revolving gun, the short-hand revolver is universally used. The revolver allows the user to fire multiple rounds without reloading, each time the user cocks the hammer, the cylinder revolves to align the next chamber and round with the hammer and barrel, which gives this type of firearm its name. In a single-action revolver, the user pulls the back with his free hand or thumb. In a double-action revolver, pulling the trigger moves the back, then releases it. Loading and unloading a double-action revolver requires the operator to swing out the cylinder and insert the proper ammunition, the first guns with multichambered cylinders that revolved to feed one barrel were made in the late 16th century in Europe. They were expensive and rare curiosities, not until the 19th century would revolvers become common weapons of industrial production. One of the first was a flintlock revolver patented by Elisha Collier in 1814, the first percussion revolver was made by Lenormand of Paris in 1820 and the first percussion cap revolver was invented by the Italian Francesco Antonio Broccu in 1833. He received a prize of 300 francs for his invention, although he did not patent it, however, in 1835 a similar handgun was patented by Samuel Colt, who would go on to make the first mass-produced revolver. The first cartridge revolvers were produced around 1854 by Eugene Lefaucheux, revolvers soon became standard for nearly all uses. In the early 20th century, semi-automatic pistols were developed, which can hold more rounds, Automatic pistols also have a flat profile, more suitable for concealed carry. Automatic pistols have almost completely replaced revolvers in military and law enforcement use, revolvers still remain popular as back-up and off-duty handguns among American law enforcement officers and security guards. Also, revolvers are still common in the American private sector as defensive, in the development of firearms, an important limiting factor was the time it took to reload the weapon after it was fired. While the user was reloading, the weapon was useless, several approaches to the problem of increasing the rate of fire were developed, the earliest being multi-barrelled weapons which allowed two or more shots without reloading. Later weapons featured multiple barrels revolving along a single axis, the earliest examples of what today is called a revolver were made in Germany in the late 16th century. These weapons featured a barrel with a revolving cylinder holding the powder

Smith & Wesson Model 1
–
The Smith & Wesson Model 1 was the first firearm manufactured by Smith & Wesson, with production spanning the years 1857 through 1882. It was the first commercially successful revolver to use rimfire cartridges instead of powder, musket ball. It is a single-action, tip-up revolver holding seven.22 Short black powder cartridges, as Samuel Colts patent on the night revolver was set to expire in 1856, Horace Smith and Daniel B. Wesson were researching a prototype for a cartridge revolver. Rather than make White a partner in their company, Smith and it would become Whites responsibility to defend his patent in any court cases which eventually led to his financial ruin, but was very advantageous for the new Smith & Wesson Company. The Model 1 had three issues or major variants, with each subsequent issue introducing significant technical changes, the 1st Issue of the Model 1 was the first major iteration, with approximately 12,000 produced over a three year period. There are six variations of the Model 1, first identified in an article by John Kountz in the April 1956 issue of The Gun Report. In this article, Kountz noted specific differences in the shield, the barrel latch. Serial numbers were issued sequentially for the Model 1 1st Issues ranging from 1 through approximately 12,000, the 2nd Issue of the Model 1 looked similar to the 1st Issue, with several notable differences. The side plate on the 2nd Issue was much larger and irregularly shaped, the profile of the frame was flatter, and the hammer was now made in one piece. Model 1 2nd Issues still had the flared, square cornered shaped grip and the octagonal tip-up style frame, there are several variations of the 2nd Issue guns. Variants between serial numbers 12,000 through to about 20,000 involve the shape of the plate, the design of the trigger spring. There was also a decrease in the size of the barrel roll stamps at around serial number 95,000, 2nd Issue marked 2D QUALTY are also seen occasionally. There were approximately 110,000 2nd Issues produced from 1860 through 1868, the Model 1, 3rd Issue represented a substantial redesign for the Model 1, with a fluted cylinder, a round barrel and a rounded birds head style grip. Finishes included full nickel plating, full blued steel, and a half plate nickel/blue combo, variants include the square and triangular top strap design that changed around serial number 9,500. The 3rd Issue guns were produced from 1868 through 1882 with serial numbers from 1 through approximately 131,000 and this popularity led to numerous knockoffs and patent infringements by other armsmakers. Rolin White and S&W brought infringement cases against Manhattan Firearms Company, Ethan Allen, Merwin & Bray, National Arms Company, the courts mostly allowed these manufacturers to continue production runs, with a royalty on each revolver paid to White. In some cases, Smith & Wesson bought the back to remark and sell

Smith & Wesson Model 1 1/2
–
Chambered in.32 Rimfire, its cylinder held 5 shots. It was produced in three varieties from 1865 through 1892, with production exceeding 223,000. The Model 1 1/2 had three issues, the first issue of the Model 1 1/2 can be identified by its smooth cylinder, and the square shape of the grip butt. Models were available in blued or nickel-plated finishes, and the majority were produced with 3 1⁄2-inch barrels, a less common 4-inch barrel variety was also sold. Serial numbers range from 1 through to approximately 26,300, the second issue of the Model 1 1/2 can be identified by its fluted barrel and the rounded shape of the grip butt. Like the 1st Issue, it was produced in blued steel and nickel-plated varieties. 2nd Issue guns were numbered consecutively after the 1st Issue. There is also a transitional model 2nd issue that uses the unfluted 1st issue barrels, the serial numbers for these transitional models span approximately 27,200 through 28,800. The third issue of the Model 1 1/2 is known as the Model No.1 1/2 Single Action Revolver and it differs substantially from the first two issues by breaking at the top, consistent with the design of the Safety Hammerless or S&W.38 Single Action. The grip is rounded at the butt, and is similar in appearance to that on the 2nd Issue and this revolver marked the debut of the.32 S&W centerfire cartridge. Serial numbers ranged from 1 to approximately 97,500

Smith & Wesson Model 3
–
Schofield, who made his own modifications to the Model 3 to meet his perceptions of the Cavalrys needs. Smith & Wesson incorporated these modifications into an 1875 design they named after the Major, the S&W Model 3 was originally chambered for the.44 S&W American and.44 Russian cartridges, and typically did not have the cartridge information stamped on the gun. Model 3 revolvers were produced in an assortment of calibers, including.44 Henry Rimfire. 44-40. 32-44. 38-44. The design would influence the smaller S&W.38 Single Action that is referred to as the Model 2. Smith & Wesson produced large numbers of the Model 3, in three models, for the Russian Empire by special order. The Russian and European copies of the S&W Model 3 revolver were generally of high quality. This led to the Imperial government cancelling the order for significant quantities of Smith & Wesson–made revolvers, and delaying payment for the handguns that had already been delivered. The U. S. Army adopted the.44 S&W American caliber Smith & Wesson Model 3 revolver in 1870, most military pistols until that point were black powder cap and ball revolvers, which were slow, complicated, and susceptible to the effects of wet weather. Smith & Wesson instead developed their own, slightly shorter.45 caliber round, when it became obvious in the field that the two cartridges would not work interchangeably in the Schofield, the U. S. Government adopted the shorter.45 Schofield cartridge as the standard cartridge. Despite the change, old stocks of the longer.45 Colt rounds in the line caused the Army to drop most of the Schofields. Many of the S&W Model 3 Schofield revolvers saw service in the Indian Wars, the Smith & Wesson No.3 revolver was famously used by Wyatt Earp during the OK Corral Gunfight with the Clanton Gang. While the standard length was 7, many Schofields were purchased as surplus by distributors, and had the barrels shortened to 5. After the Spanish–American War of 1898, the US Army sold off all their surplus Schofield revolvers and these revolvers were then inspected by the Wells Fargo armorer and uniquely stamped W. F. Lieutenant Colonel Schofield shot himself on December 17,1882, with a S&W Schofield revolver after suffering a bout of illness, stress. The Schofield was produced in various versions, the First Model Schofield has a latch configuration that is rather pointed at the top and has a circle around the screw head at the bottom. The Second Model latch has a raised circle at the top of the latch. In the previous engineering, the posts of the frame would wear out after heavy usage, Schofields improvement called for heat treated, replaceable components at this sensitive wear area of the catch and latch. The serial number range also will give an indication of whether it is First or Second Model, in 1877, S&W discontinued production of its other Model 3s such as the American, Russian, and Schofield—in favor a new improved design called the New Model Number Three

Smith & Wesson Safety Hammerless
–
The Smith & Wesson Safety Hammerless or Smith & Wesson New Departure is a double-action revolver that was produced from 1887 to 1940 by Smith & Wesson. The revolver incorporated an internal hammer and a grip safety on its backstrap. It was chambered in.32 S&W and.38 S&W calibers, the grip safety made a brief return to Smith & Wessons revolvers in 1952 with the release of the Models 40 and 42. The Smith & Wesson.38 Safety Hammerless models were produced from 1887 to just before World War II and they were chambered in either.32 S&W or.38 S&W with a five-shot cylinder. They were most often produced with a 2-inch, 3-inch, or 3. 5-inch barrels and these top-break revolvers were designed for fast reloading and concealed carry as the hammer was internal and would not snag on drawing the revolver from a pocket. They were known as The New Departure to reflect the new approach to designing revolvers. Minor design changes were made to these revolvers over the years, resulting in different design models. The first model was manufactured between 1887-1902, the 38 was based on S&Ws medium frame, while the 32 was based on the smaller sized 1½ frame. In 1952 the safety hammerless concept was applied to Smith & Wessons J-frame, the finished product became the Model 40 and 42 chambered in.38 Special and is alternately known as the Centennial as it was produced in the 100th anniversary of the founding of Smith & Wesson. While few competitors replicated the grip safety, the hammer or hammerless design proved popular with other manufacturers such as Iver Johnson and Harrington & Richardson. The concept is still maintained by numerous modern double-action revolver manufacturers

Smith & Wesson Model 10
–
In production since 1899, it is a six-shot double-action revolver with fixed sights. Over its long run it has been available with barrel lengths of 2 in,3 in,4 in,5 in. Barrels of 2.5 inches are also known to have made for special contracts. Some 6,000,000 of the type have been produced over the years, making it the most popular centerfire revolver of the 20th century. In 1899, the United States Army and Navy placed orders with Smith & Wesson for two to three thousand Model 1899 Hand Ejector revolvers chambered for the M1892.38 Long Colt U. S, in 1902 the.38 Military & Police was introduced, featuring substantial changes. These included major modification and simplification of the internal lockwork and the addition of a locking underlug on the barrel to engage the previously free-standing ejector rod, barrel lengths were 4,5,6, and 6.5 inches with a rounded butt. Serial numbers for the Military & Police ranged from number 1 in the series to 20,975, most of the early M&P revolvers chambered in.38 Special appear to have been sold to the civilian market.

Army helicopter crew members, criminal Investigation Division agents were issued.38 caliber revolvers with two inch barrels. The Victory Model remained in use with Air National Guard tanker, rechambering of. 38-200 cylinders to.38 Special results in oversized chambers, which may cause problems. Lee Harvey Oswald was carrying a re-chambered Victory Model when he was apprehended on November 22,1963, other distinguishing features of the Victory Model revolver are the lanyard loop at the bottom of the grip frame, and the use of smooth walnut grip panels. However some early models did use a grip, most notably the pre-1942 manufacture. After World War II, Smith & Wesson returned to manufacturing the M&P series, in 1957, Smith & Wesson adopted the convention of using numeric designations to distinguish their various models of handguns, and the M&P was renamed the Model 10. The M&P/Model 10 has been available in blued steel finish and nickel finish for most of its production run. The model has also offered throughout the years with both the round butt and square butt, i. e. grip patterns

Smith & Wesson Model 12
–
The Smith & Wesson Model 12 is.38 Special revolver on Smith & Wessons medium-sized K-frame. It is an aluminium alloy-frame version of the Model 10 and it was made from 1953 to 1986 in both two- and four-inch barrel configurations. Early models used a cylinder as well as frame.38 Special. Some 40,000 Smith & Wesson M13 revolvers were produced, a civilian model of the M13 was released in 1953, called the Military & Police Airweight. This designation was changed in 1957 to the Model 12 Airweight, the Military & Police Airweight initially used both an aluminum cylinder and frame, and weighed only 14.5 ounces. The Model 12 variants 12-1, 12-2, and 12-3 used a hammer and had an aluminum grip frame that was 0. 08-inch narrower than the standard steel K-frame. The final version, the Model 12-4, used the standard frame dimension of the other K-frames and it also featured a rounded butt. Pre-Model 12 - predates model number markings and it has an alloy cylinder and will be a 5 screw design with 4 sideplate screws and a screw in front of the trigger guard. This is apparent when the primers have elongated firing pin marks, very early versions have aluminum cylinders and should not be fired. The two-inch barrel Model 12 is also called a snub-nose and it is also a proven performer as a back-up pistol for some officers, who carry a larger caliber pistol at their waist. The Model 12 is most often found to have some wear on its due to age. An important earmark is the factory stamp Mod-12 on the frame inside the yoke, also on the inside of the yoke is the revolvers serial number, which is repeated verbatim on the base of the butt. The Model 12 holds its market value nicely and is highly collectible, as with most older revolvers, a reputable gunsmith should check its functioning prior to purchase

It is chambered for the.38 Special cartridge and is fitted with a 4-inch barrel, originally known as the K-38 Combat Masterpiece, it was renamed the Model 15 in 1957 when all Smith & Wesson revolvers were given numerical model numbers. The main production run of the Model 15 was from 1949 through 1999 and it was discontinued for approximately a decade until 2011, when a re-tooled version was re-released under S&Ws Classics Revolvers line. The Smith & Wesson K-38 Combat Masterpiece Revolver Model 15 is a derivative of the classic 1899 K-frame Military, the M&P underwent steady evolution throughout the 20th century and S&W spun off several variations as separate models in the post World War II years. One of these was the K-38 Target Masterpiece, which production in 1947. 375” short-throw hammer, a trigger adjustment for overtravel. Noting the accuracy of the Target Masterpiece, a number of departments and the FBI soon requested the same revolver with a four-inch barrel. The result was the K-38 Combat Masterpiece, the major distinction between the K-38 Target Masterpiece and the K-38 Combat Masterpiece is the barrel length and the front sight. In 1957 the K-38 Combat Masterpiece was renamed the Model 15 when all Smith & Wesson revolvers were given model numbers. The model number is stamped on the frame behind the cylinder yoke, a number of production and engineering changes have been made throughout the years, some of which are noted by a dash number suffixed to the Model number. Over the years the Model 15 has been produced with several barrel lengths, in 1972 S&W released a stainless steel version as the Model 67. These two safety systems work oppositely, but achieve the goal of only allowing the gun to fire when the trigger is pulled all the way. The Model 15 was a sidearm for law enforcement and was the standard issue sidearm of the U. S. Air Force Police from 1962 until 1992 when it was replaced by the Beretta M9 pistol. Production of the Model 15 was discontinued in 1999 when Smith & Wesson was purchased and reorganized, in 2011 Smith & Wesson re-introduced the Model 15 under their Classics Revolvers line, newly machined, with a shrouded redesigned barrel, and a built-in trigger lock.

Smith & Wesson Model 17
–
The Smith & Wesson Model 17 is a six-shot double-action revolver chambered for.22 LR. It is built on Smith & Wessons medium-sized K-frame, Smith & Wessons Models 16 and 17 have their origins with the companys Pre-World War 2 Hand Ejector series in the 1930s. These two revolver models debuted as companion pieces known as the Models K-32 and K-22 after World War 2, the K-32 Masterpiece debuted in 1935 and was chambered in.32 S&W Long caliber. Production ceased during World War 2 and the revolver was reintroduced in 1947 along with the K-22 Masterpiece in.22 Long Rifle caliber, the Model 17 has an adjustable rear sight and an un-pinned, fixed ramp or Patridge style front sight. It was designed as a revolver and could be ordered from S&W with The Three Ts, Target Trigger, Target Hammer. Standard barrel lengths were 4,6 and 8 3/8, the 4 model 17-6 is infrequently seen, as S&W produced the almost identical,4 barrelled, Model 18. The Model 18 was a Model 17 copy- except the 4 barrel was tapered where the Model 174 barrel was not. Many collectors believe the Model 17-6 with the 4 non-tapered barrel was a bit of a production oddity, in 1990, S&W also shipped the Model 17 featuring a 4,6 or 8 3/8 full under lug barrel. The under lug was a solid, blued steel, circular rod, cast as part of the barrel, the under lug not only enclosed the ejector rod, it also added considerable weight to the gun itself. The under lug model shipped with a round butt wood grip that featured inletted finger grooves. The 4 Model 17 Under Lug is infrequently seen and quite possibly manufactured as an afterthought using factory shortened 6 or 8 3/8 under lug barrels. Model 617 - At the same time S&W introduced the Model 17 full Under Lug and this is the stainless steel version of the blued steel Model 17.22 LR, however all Model 617s have full, Under Lug barrels. Offered in the same three barrel lengths as the Model 17, the 617 is still in current production and is shipped with rubber grips, the Model 617 is found with a six-shot or ten-shot, steel.22 LR cylinder. The only exception is the early production Model 617-2 which was made with a ten-shot, later dash 2 617s were shipped with stainless steel cylinders. Photograph of Model 53 with cylinder inserts.

The.357 Magnum is the oldest magnum handgun cartridge, Smith & Wesson played a major part in the development and success of the cartridge and revolver that went with it. Firearms writer and experimenter Philip Sharpe is credited for its development during the 1930s when police agencies were asking for a more powerful round. S&Ws Dan Wesson agreed to produce a new revolver that would handle high-intensity.38 Special loads, but only if Winchester would develop a new cartridge. Winchester introduced the.357 Magnum, which was identical to the.38 Special except for a.125 inch longer case. Retired Assistant Chief Patrol Inspector of the U. S, border Patrol, famous gunfighter, and noted firearms and shooting skills writer Bill Jordan consulted with Smith & Wesson on the design and characteristics of the Model 19. Jordans idea for a peace officers dream sidearm was a heavy-barreled four-inch K-Frame.357 Magnum with a shrouded barrel like the big N-frame.357 and adjustable sights. The.357 Magnum, four-inch barreled model was standard issue to uniformed officers of the former U. S. Immigration and Naturalization Service as well as Patrol Agents of the U. S, border Patrol until both agencies adopted.40 caliber semi-automatic pistols. The.357 Magnum,2. 5” barreled model was standard issue to Special Agents of the former U. S. Immigration and Naturalization Service as well as Patrol Agents of the U. S. Border Patrol working plain clothes assignments until both agencies adopted.40 caliber semi-automatic pistols.5,4, or 6-inch barrel lengths, the weights are 30.5 ounces,36 ounces, and 39 ounces, respectively. The 2. 5- and 3-inch barrel versions had round butts, the Model 19 was produced from 1957 to November 1999. The Model 66 was produced from 1970 until 2005, the Model 66 differed by its use of stainless steel and its smooth target-type trigger. The Model 19 and the Model 66 had the same trigger options, engineering changes were designated with a dash- number after the model number. The engineering changes are as follows,19, Stamping of model number, 19-1, Change extractor rod, right to left-hand thread. 19-2, Cylinder stop changed, deleted triggerguard screw,50 manufactured with 2.5 barrel, serial range K544672–K544721. 19-3, Relocation of rear sight leaf screw, 19-4, Change gas ring from yoke to cylinder. 19-5, Eliminate cylinder counterbore and pinned barrel, small change in length to 1.62

Smith & Wesson Model 586
–
The Smith & Wesson Model 586, is a six- or seven-shot double-action revolver chambered for the.357 Magnum cartridge. It is essentially the same weapon as the S&W Model 686, also, since the 586 was directed more to law enforcement, most have shorter barrels than the 686. It will chamber and fire.38 Special cartridges, as the.357 Magnum was developed from the.38 Special, the magnum case is slightly longer to prevent magnum rounds from being chambered and fired in handguns chambered for the.38 Special. The Model 586 uses S & Ws L revolver frame, with a K-Frame sized grip mated to a larger diameter cylinder, during the 1980s, Smith & Wesson developed its L-Frame line of.357 Magnums, the Model 581, Model 586, Model 681 and Model 686. The Model 581 had a fixed notch type rear sight, whereas the 586 used a target style adjustable rear sight and these handguns had a major effect on both law enforcement and sporting markets. The 586 was introduced in 1980 and the 581 was discontinued in 1988, according to Jim Supica and Richard Nahas in their book Standard Catalog of Smith & Wesson, 3rd Edition The K-frame.357 magnum revolvers became immensely popular as police revolvers. However some felt that extensive firing of full power.357 ammunition in the relatively light framed guns was wearing on both gun and shooter. There appeared to be a demand for a.357 that handled like a K frame but offered the heft, the L frame was introduced as this compromise size, with design input from Roy Jinks, and quickly established itself in the law enforcement and hunting markets. L frames also feature a full-length under-barrel lug, which adds recoil-absorbing weight to the gun. It was manufactured in blue or nickel-plated versions. A stainless steel version exists as the Model 686, other variations, such as the Model 686+, chambered for 7 rounds, are available. In the late 1990s, Smith & Wesson discontinued production of all but a few blued revolvers, thus the Model 686, in 2012, Smith & Wesson brought back the 586 in its 4-in. and 6-in.

Smith & Wesson Ladysmith
–
The S&W Ladysmith and LadySmith are a series of handguns manufactured by Smith & Wesson starting early in the 20th century. Smith & Wesson has produced firearms over the years in standard frame sizes. M-frame refers to the small early Ladysmith frame, later LadySmith small revolvers were made on the somewhat larger J-frame, the standard S&W small-frame revolver. The tiny M-frame.22 hand-ejector Ladysmith revolver was produced from 1902 through 1921, during the 1980s, prior to the 1986 FBI Miami shootout, the Federal Bureau of Investigation adopted a revolver very similar to the Model 65 Ladysmith, but without the moniker. Smith & Wesson Model 60 LadySmith, known as the Chiefs Special LadySmith and it has a stainless steel slide with an aluminum alloy frame. The 3913LS had a different look to the slide and frame and it is chambered for 9mm only. It has a 3.5 inch barrel and the magazine holds eight rounds and it is one of their third generation semi-automatic pistols that S&W refers to as a traditional double action. After the pistol fires that first time, the pistol is in what is called single action, wherein the hammer stays cocked and it is the firing pin block that makes dropping the hammer with the decocker safe, albeit somewhat unnerving. The original 3913 has been popular with law enforcement officers that need to carry their primary sidearm concealed, the Lady Smith is very flat because it has a single-stack magazine and only a single thumb safety on the left side compared to the two-sided ambidextrous safety on the 3913NL. As of 2013, the models still in production are the 60LS

Smith & Wesson Triple Lock
–
The Triple lock, officially the Smith & Wesson.44 Hand Ejector 1st Model New Century, is a double-action revolver. It was and is considered by many, including handgun enthusiast and expert Elmer Keith and its popular name refers to its extra locking lug on the cylinder crane. This extra locking mechanism was deemed due to the increased power of the.44 Special cartridge. These 19th-century designs had an automatic ejector mechanism actuated when the frame was tipped up, the newer Hand Ejector models required the user to depress a plunger to eject spent cartridge casings. The New Century designation was in recognition of its status as Smith & Wessons first 20th century design and it was only manufactured between 1908 and 1915, for a total of 15,376 revolvers, a stock that sold out completely by 1917. It was replaced by a.44 Hand Ejector 2nd Model, most visibly different in lacking the ejector shroud, the British and Canadian militaries pressed for the removal of the third locking lug and shroud due to concerns the precision mechanism would collect dirt and malfunction. Additionally, the change simplified manufacturing, allowing Smith & Wesson to drop the price of the gun by $2, the ejector shroud was reintroduced in 1926, with the Hand Ejector 3rd Model, but the Triple Lock feature was never used again. To cover manufacturing shortages of the Webley Mk VI, early in the war the Ministry of Munitions contracted Colt, subsequent orders, lacking the third locking lug and ejector shroud, totalled 69,755 and were known as the Mark II.

Smith & Wesson .38/44
–
High-pressure. 38/44 loadings represent a transition between conventional.38 Special ammunition and the.357 Magnum. Revolvers were manufactured from 1930 to 1941, and after World War II until lower-priced.357 Magnum revolvers became widely available. In 1930, Smith & Wesson chambered their large framed.44 Special revolver for.38 Special with a 5-inch barrel and fixed sights intended for police use, a 4-inch barrel was offered in 1935 for users willing to accept the reduced ballistic performance of a more compact firearm. The media attention gathered by the. 38/44 and its ammunition encouraged Smith & Wesson to develop the longer.357 Magnum cartridge in 1935, the. 38/44 was an option for purchasers unwilling to pay the premium pricing of.357 Magnum revolvers. Revolvers were available with blue or nickel finish. Production was interrupted by the world war. Postwar production serial numbers are prefixed with the letter S, the Outdoorsman with adjustable sights became the Smith & Wesson Model 23 after 1957 and the fixed sight Heavy Duty version was marketed as the Smith & Wesson Model 20

The Model 28, also known as the Highway Patrolman, traces its heritage back to the Smith & Wesson Registered Magnum, the Registered Magnum morphed into the Model 27. Law enforcement agencies favored the Model 27, but its high-polish finish, the Model 28 is unusual in that Smith & Wesson removed, rather than added, features to the Model 27 to create it, in order to reduce production costs with no reduction in utility. A classic N frame revolver, the Highway Patrolman is blued, the top strap and frame rounds are bead blasted to achieve a matte appearance. By the early 1950s Smith & Wesson returned to manufacturing many of its pre-World War II models, including the.357 Magnum, however, the.357 Magnum was more costly than the standard.38 special revolver of the time. In the late 1940s and the first part of the 1950s Smith & Wesson was the only American gun company manufacturing a.357 magnum revolver.357 magnum revolver, S&W responded with the Highway Patrolman.

Smith & Wesson Model 29
–
The Smith & Wesson Model 29 is a six-shot, double-action revolver chambered for the.44 Magnum cartridge and manufactured by the U. S. company Smith & Wesson. The Model 29 was offered with 3,4,5,6, 6½, 8⅜ and, later, other barrel lengths were available either by special order from Smith & Wessons Custom Shop or custom built by gunsmiths. The 5 barreled variant had a full length underlug, finish options available included a highly polished blued or nickel-plated surface. At the time of its introduction, the Model 29 was the most powerful production handgun and it was made famous by association with the fictional character Dirty Harry Callahan. The Model 29 will chamber and fire.44 Special cartridges, the Magnum case is slightly longer to prevent magnum rounds from being chambered and fired in handguns chambered for the.44 Special. Elmer Keiths achievements in maximizing the power and performance of the.44 Special was the inspiration, S&Ws production of a large N-frame revolver in.44 Magnum began in 1955, the Model 29 designation was applied in 1957. At the time of its introduction, the Model 29 was the most powerful production handgun, there were a number of custom calibers that were more powerful, as in the old Howdah pistols of the 19th century. After the movies release, retailers had trouble keeping the Model 29 in stock, the original Model 29 was superseded by the Model 29-1 in 1960, with modifications made to the ejector-rod screw. The Model 29-2 replaced it the year, with one screw that had secured the cylinder-stop spring being deleted. The barrel length was shortened from 6 1/2 to 6 in 1979 and these two versions are known as pinned and recessed. Pinned means that the barrels are screwed in, and secured by a pin driven through the frame, recessed denotes the rear of the bored cylinder holes being countersunk, so that, when loaded, the cartridge rims are fully enclosed by the cylinder. In 1982, the cost-cutting Model 29-3 dropped recessed cylinders and pinned barrels for crush-fit barrels, the -4 and -5, produced from 1988 and 1990 respectively had changes to improve durability for heavy use. In 1994 the 29-6 began production, now fitted as standard with rubber Monogrips from Hogue to replace the wooden items. The 29-7 started production in 1998 with changes to the mechanism, the firing pins attachment. Introduced in 1978, the Smith & Wesson Model 629 is a steel version of the Model 29. The 629 Classic variant features a full-length barrel underlug, other include the 629 Stealth Hunter.

Smith & Wesson Model 57
–
The gun was designed as a weapon for law enforcement agencies. However, due to size and recoil it found favor with civilian target shooters and hunters. In April 1964 Remington responded by introducing the.41 Magnum cartridge, elmer Keith originally proposed the name.41 Police for the new cartridge, but Remington instead chose.41 Magnum, hoping to capitalize on the notoriety and popularity of its earlier Magnum offerings. First introduced in April 1964, the Model 57 was produced with 4,6, 6-1/2, and 8-3/8 barrels in both highly polished blued and nickel–plated finishes. Like the Model 29, the 57 sported a red insert front sight with a white outline adjustable rear iron sight, as well as a target trigger, target hammer. Remington originally offered two ammunition loadings in its.41 Magnum cartridge lineup, the second loading was a less powerful 1,150 ft/s 210 grain lead semiwadcutter intended for law enforcement usage. Due to a number of factors the.41 Magnum unfortunately never became the next great police loading that its developers and supporters envisioned. Also, the decision by S&W and Remington to dub the cartridge a Magnum ended up working against them in their desire to address the law enforcement market. Although the.41 Magnum was adopted as a police departmental standard by a few such as Amarillo and San Antonio TX. In addition, introduced in the shadow of its big brother the.44 Magnum Model 29. This gap widened further when Clint Eastwood used a Most powerful hangun in the world Model 29 in the popular film Dirty Harry. In the aftermath of the release, many contemporaries of the.44 Magnum, including the.41, somewhat fell out of favor with the general public. Finally, a series of popular and successful lighter and smaller-framed revolvers crafted from stainless steel emerged in the mid 1980s. These police-issue oriented firearms, exemplified by such as the S&W Model 66. Overall, the Model 57 and its variants failed to generate the interest which had hoped for. Smith & Wesson offered an all stainless steel version of the Model 57 as the Model 657, the Model 657 was introduced in 1986. A very rare 5 model 57 was produced in the custom shop, all known examples included the traditional short underlug/ejector shroud. On July 10,1964, S&W introduced a more basic and this budget version of the Model 57 was similar in principle of design to the.38 Special S&W heavy-barrel Model 10, or.357 Magnum Model 28 Highway Patrolman
