Pistol
–
A pistol is a type of handgun. In some usage, the term refers to a subset of handguns. In other usage, the term is interchangeable with handgun, some handgun experts and dictionaries make a technical distinction that views pistols as a subset of handguns, others use the terms interchangeably. But UK/rest of Commonwealth usage does not always make this distinction, for example, the official designation of the Webley Mk VI revolver was Pistol, Revolver, Webley, No.1 Mk VI. The English word was introduced in ca.1570 from the Middle French pistolet, the etymology of the French word pistolet is disputed. The first suggestion derives the word from Czech píšťala, a type of hand-cannon used in the Hussite Wars during the 1420s, the Czech word was adopted in German as pitschale, pitschole, petsole, and variants. The second suggestion is less likely, the use of the word as a designation of a gun is not documented before 1605 in Italy, long after it was used in French, the Czech word is well documented since the Hussite wars in 1420s. Other suggestions include from Middle High German pischulle or from Middle French pistole, also it is suggested that early pistols were carried by cavalry in holsters hung from the pommel of a horses saddle. The most common types of pistol are the shot. Single shot handguns were mainly seen during the era of flintlock and musket weaponry where the pistol was loaded with a ball and fired by a flint striker. However, as technology improved, so did the single shot pistol, new operating mechanisms were created, and due to this, they are still made today. It is the oldest type of pistol, and is used to hunt wild game. Multi-barreled pistols were common during the time as single shot pistols. As designers looked for ways to increase fire rates, multiple barrels were added to all guns including pistols, one example of a multi-barreled pistol is the Ducks foot pistol, which generally had either four or eight barrels, although some 20th century models had three barrels. Around 1850, pistols such as the Jarre harmonica gun were produced that had a sliding magazine, the sliding magazine contained pinfire cartridges or speedloaders. The magazine needed to be moved manually in many designs, hence distinguishing them from semi-automatic pistols, with the development of the revolver in the 19th century, gunsmiths had finally achieved the goal of a practical capability for delivering multiple loads to one handgun barrel in quick succession. The semi-automatic pistol was the step in the development of the pistol. By avoiding multiple chambers—which need to be individually reloaded—semi-automatic pistols delivered faster rates of fire, an example of a modern blow back action semi-automatic pistol is the HK VP70

United States
–
Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the northwest corner of North America, bordered by Canada to the east, the state of Hawaii is an archipelago in the mid-Pacific Ocean. The U. S. territories are scattered about the Pacific Ocean, the geography, climate and wildlife of the country are extremely diverse. At 3.8 million square miles and with over 324 million people, the United States is the worlds third- or fourth-largest country by area, third-largest by land area. It is one of the worlds most ethnically diverse and multicultural nations, paleo-Indians migrated from Asia to the North American mainland at least 15,000 years ago. European colonization began in the 16th century, the United States emerged from 13 British colonies along the East Coast. Numerous disputes between Great Britain and the following the Seven Years War led to the American Revolution. On July 4,1776, during the course of the American Revolutionary War, the war ended in 1783 with recognition of the independence of the United States by Great Britain, representing the first successful war of independence against a European power. The current constitution was adopted in 1788, after the Articles of Confederation, the first ten amendments, collectively named the Bill of Rights, were ratified in 1791 and designed to guarantee many fundamental civil liberties. During the second half of the 19th century, the American Civil War led to the end of slavery in the country. By the end of century, the United States extended into the Pacific Ocean. The Spanish–American War and World War I confirmed the status as a global military power. The end of the Cold War and the dissolution of the Soviet Union in 1991 left the United States as the sole superpower. The U. S. is a member of the United Nations, World Bank, International Monetary Fund, Organization of American States. The United States is a developed country, with the worlds largest economy by nominal GDP. It ranks highly in several measures of performance, including average wage, human development, per capita GDP. While the U. S. economy is considered post-industrial, characterized by the dominance of services and knowledge economy, the United States is a prominent political and cultural force internationally, and a leader in scientific research and technological innovations. In 1507, the German cartographer Martin Waldseemüller produced a map on which he named the lands of the Western Hemisphere America after the Italian explorer and cartographer Amerigo Vespucci

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

10mm Auto
–
The 10mm Auto is a semi-automatic pistol cartridge first developed by Jeff Cooper and introduced in 1983 with the Bren Ten pistol. Its design was improved, then produced initially by ammunition manufacturer FFV Norma AB of Åmotfors. The 10mm Auto cartridge was originally drafted and championed by eminent firearms expert Lieutenant Colonel John Dean Jeff Cooper and it was designed to be a medium-velocity pistol cartridge with better external ballistics than the.45 ACP and capable of greater stopping power than the 9×19mm Parabellum. When FFV Norma AB designed the cartridge at the behest of Dornaus & Dixon Enterprises, Inc. for their Bren Ten pistol, the company decided to increase the power over Coopers original concept. The case was derived from the.30 Remington rifle round, cut down, an example being the peculiar circumstances surrounding the pistols distribution at its primary release, leading to a number of initial Bren Tens sent to dealers and customers without magazines. In the succeeding five years, prices on the Standard Model rose to in excess of U. S. $1,400, since 1994, both units still field the weapon and caliber to this day. Thereafter, experimentations were carried out and a specification for reduced-recoil ammunition was created, the requirement was later submitted to the Federal Cartridge Corporation for production and followed further review. This became known as the 10mm Lite, or 10mm FBI load and this altered cartridge was named the.40 Smith & Wesson. In 2015 SIG Sauer entered the 10mm marketplace with their P220 model chambered in 10mm, the 10mm outperforms the.40 S&W by 270–300 ft/s for similar bullet weights when using available full power loads, as opposed to the 10mm FBI level loads still found in some ammunition catalogs. The 10mm Auto has 1.56 milliliter cartridge case capacity. Common rifling twist rate for this cartridge is 406.40 mm,6 grooves, Ø lands =9.91 mm, Ø grooves =10.17 mm, a large pistol primer is used. The Commission Internationale Permanente pour lEpreuve des Armes à Feu Portatives rulings indicate a maximum pressure of 230 MPa, regulated countries, every pistol/cartridge combination is required to be proofed at 130% of this maximum C. I. P. pressure to certify for sale to consumers. The Sporting Arms and Ammunition Manufacturers Institute maximum pressure limit for the 10mm Auto is set at 37,500 psi, at full potential, the 10mm Auto produces energy slightly higher than an average.357 Magnum load and below standard.41 Magnum rounds. The cartridge is considered to be high-velocity, giving it a flight path upon firing relative to other handgun cartridges. In its lighter loadings, the 10mm Auto is a duplicate of the.40 S&W cartridge. More powerful loadings can equal or exceed the performance of the.357 Magnum, and retain more kinetic energy at 100 yards than the.45 ACP has at the muzzle. The 10mm Auto is marketed for hunting, defensive, and tactical use and is one of the few semi-automatic, the round makes the Major power factor ranking in the International Practical Shooting Confederation, even in lighter loadings. In military use, the government of Denmark has issued the Glock 20 to the Slædepatruljen Sirius headquartered in Daneborg, the pistols were issued as a defense against polar bears which the unit encounters during patrols

Bullet
–
The word bullet is a firearm term. A bullet is a projectile expelled from the barrel of a firearm, the term is from Middle French and originated as the diminutive of the word boulle which means small ball. Bullets are made of a variety of materials and they are available singly as they would be used in muzzle loading and cap and ball firearms, as part of a paper cartridge, and much more commonly as a component of metallic cartridges. Bullets are made in a numbers of styles and constructions depending on how they will be used. Many bullets have specialized functions, such as hunting, target shooting, training, defense, a bullet is not a cartridge. In paper and metallic cartridges a bullet is one component of the cartridge, bullet sizes are expressed by their weight and diameter in both English and Metric measurement systems. For example.22 caliber 55 grain bullets or 5. 56mm 55 grain bullets are the same caliber, the word bullet is often used colloquially to refer to a cartridge, which is a combination of the bullet, paper or metallic case/shell, powder, and primer. This use of bullet, when cartridge is intended, leads to confusion when the components of a cartridge are discussed or intended, the bullets used in many cartridges are fired at a muzzle velocity faster than the speed of sound. Meaning they are supersonic and thus can travel a substantial distance, bullet speed through air depends on a number of factors such as barometric pressure, humidity, air temperature, and wind speed. Subsonic cartridges fire bullets slower than the speed of sound and so there is no sonic crack and this means that a subsonic cartridge such as.45 ACP can be effectively suppressed to be substantially quieter than a supersonic cartridge such as the.223 Remington. Bullets do not normally contain explosives, but damage the target by impact. The first use of gunpowder in Europe was recorded in 1247 and it had been used in China for hundreds of years. Later in 1364 hand cannon appeared, early projectiles were made of stone. Stone was used in cannon and hand cannon, in cannon it was eventually found that stone would not penetrate stone fortifications which gave rise to the use of heavier metals for the round projectiles. Hand cannon projectiles developed in a similar following the failure of stone from siege cannon. The first recorded instance of a ball from a hand cannon penetrating armor occurred in 1425. In this photograph of shot retrieved from the wreck of the Mary Rose which was sunk in 1545, the round shot are clearly of different sizes and some are stone while others are cast iron. The development of the hand culverin and matchlock arquebus brought about the use of cast lead balls as projectiles, bullet is derived from the French word boulette, which roughly means little ball

Grain (unit)
–
A grain is a unit of measurement of mass, and, for the troy grain, equal to exactly 7001647989100000000♠64.79891 milligrams. It is nominally based upon the mass of a seed of a cereal. From the Bronze Age into the Renaissance the average masses of wheat, rather, expressions such as thirty-two grains of wheat, taken from the middle of the ear appear to have been ritualistic formulas, essentially the premodern equivalent of legal boilerplate. Another book states that Captain Henry Kater, of the British Standards Commission, the grain was the legal foundation of traditional English weight systems, and is the only unit that is equal throughout the troy, avoirdupois, and apothecaries systems of mass. The unit was based on the weight of a grain of barley. The fundamental unit of the pre-1527 English weight system known as Tower weights, was a different sort of known as the wheat grain. The Tower wheat grain was defined as exactly 45⁄64 of a troy grain.79891 milligrams, 7000100000000000000♠1 gram is approximately 7001154323600000000♠15.43236 grains. The unit formerly used by jewellers to measure pearls, diamonds, or other stones, called the jewellers grain or pearl grain, is equal to 1⁄4 of a carat. The grain was also the name of a traditional French unit equal to 6995531150000000000♠53.115 mg. In both British Imperial and U. S. customary units, there are precisely 7,000 grains per avoirdupois pound, the grain is commonly used to measure the mass of bullets and propellants. The term also refers to a particle of gunpowder, the size of which varies according to requirements. In archery, the grain is the unit used to weigh arrows. In dentistry, gold foil, used as a material to restore teeth, is measured in grains, in North America, the hardness of water is often measured in grains per US gallon of calcium carbonate equivalents. Otherwise, water hardness is measured in the metric unit parts per million, one grain per US gallon is approximately 6995171000000000000♠17.1 ppm. Soft water contains 1–4 gpg of calcium carbonate equivalents, while hard water contains 11–20 gpg, though no longer recommended, grains are still used occasionally in medicine as part of the apothecaries system, especially in prescriptions for older medicines such as aspirin or phenobarbital. For example, the dosage of a standard 6996325000000000000♠325 mg tablet of aspirin is sometimes given as 7000500000000000000♠5 grains, in that example the grain is approximated to 6995650000000000000♠65 mg, though the grain can also be approximated to 6995600000000000000♠60 mg, depending on the medication and manufacturer. The apothecaries system has its own system of notation, in which the symbol or abbreviation is followed by the quantity in lower case Roman numerals. For amounts less than one, the quantity is written as a fraction, or for one half, therefore, a prescription for tablets containing 325 mg of aspirin and 30 mg of codeine can be written ASA gr

Rifling
–
In firearms, rifling consists of helical grooves in the internal surface of a guns barrel, which impart a spin to a projectile around its long axis. This spin serves to stabilize the projectile, improving its aerodynamic stability. Rifling is often described by its twist rate, which indicates the distance the rifling takes to complete one revolution, such as 1 turn in 10 inches. A shorter distance indicates a faster twist, meaning that for a given velocity the projectile will be rotating at a spin rate. Barrels intended for long, small-diameter bullets, such as the ultra-low-drag, 80-grain 0.223 inch bullets, extremely long projectiles such as flechettes may require high twist rates, these projectiles must be inherently stable, and are often fired from a smoothbore barrel. Muskets were smoothbore, large caliber weapons using ball-shaped ammunition fired at low velocity. Due to the high cost and great difficulty of manufacturing, and the need to load readily from the muzzle. Consequently, on firing the ball bounced off the sides of the barrel when fired, barrel rifling was invented in Augsburg, Germany in 1498. In 1520 August Kotter, an armourer of Nuremberg, Germany improved upon this work, though true rifling dates from the mid-16th century, it did not become commonplace until the nineteenth century. The most successful weapons using rifling with black powder were breech loaders such as the Queen Anne pistol, the grooves most commonly used in modern rifling have fairly sharp edges. More recently, polygonal rifling, a throwback to the earliest types of rifling, has become popular, polygonal barrels tend to have longer service lives because the reduction of the sharp edges of the land reduces erosion of the barrel. Supporters of polygonal rifling also claim higher velocities and greater accuracy, polygonal rifling is currently seen on pistols from CZ, Heckler & Koch, Glock, Tanfoglio, and Kahr Arms, as well as the Desert Eagle. Such guns have achieved significant increases in velocity and range. Examples include the South African G5 and the German PzH2000, gain-twist rifling begins with very little change in the projectiles angular momentum during the first few inches of bullet travel after ignition during the transition from chamber to throat. This enables the bullet to remain undisturbed and trued to the case mouth. After engaging the rifling the bullet is progressively subjected to accelerated angular momentum as burning powder propels it down the barrel. By only gradually increasing the rate, torque is spread along a much longer section of barrel. Gain-twist rifling was used as early as the American Civil War, colt Army and Navy revolvers both employed gain-twist rifling

Primer (firearms)
–
In firearm ballistics, the primer is a component of pistol, rifle, and shotgun rounds. Early primers were simply the same black powder used to fire the weapon and this external powder was connected though a tube in the barrel that led to the main charge. As powder wont burn when wet, this led to difficulty, or even the inability, modern primers are shock sensitive chemicals. In smaller weapons the primer is usually integrated into the rear of a cartridge, in larger weapons like cannon the primer is a separate component placed inside the barrel to the rear of the main propellant charge. The first step to firing a firearm of any sort is igniting the propellant, the earliest firearms were cannons, which were simple closed tubes. There was an aperture, the touchhole, drilled in the closed end of the tube. This hole was filled with finely ground powder, which was ignited with a hot ember or torch. With the advent of firearms, this became an undesirable way of firing a gun. The first attempt to make the process of firing a small arm easier was the matchlock, the matchlock incorporated a lock that was actuated by a trigger, originally called a tricker. The lock was a lever which pivoted when pulled. The match was a burning fuse made of plant fibers that were soaked in a solution of nitrates, charcoal, and sulfur. This slow-match was ignited before the gun was needed, and it would slowly burn, after the gun was loaded and the touchhole primed with powder, the burning tip of the match was positioned so that the lock would bring it into contact with the touchhole. To fire the gun, it was aimed and the trigger pulled and this brought the match down to the touchhole, igniting the powder. With careful attention the slow-burning match could be burning for long periods of time. The next revolution in technology was the wheel-lock. It used a spring-loaded, serrated steel wheel which rubbed against a piece of iron pyrite, a key was used to wind the wheel and put the spring under tension. Once tensioned, the wheel was held in place by a trigger, when the trigger was pulled, the serrated edge of the steel rubbed against the pyrite, generating sparks. These sparks were directed into a pan, called the flash pan, the flashpan usually was protected by a spring-loaded cover that would slide out of the way when the trigger was pulled, exposing the powder to the sparks

Rim (firearms)
–
A rim is an external flange that is machined, cast, molded, stamped or pressed around the bottom of a firearms cartridge. Thus, rimmed cartridges are sometimes called flanged cartridges, almost all cartridges feature an extractor or headspacing rim, in spite of the fact that some cartridges are known as rimless cartridges. These types are rimmed, rimless, semi-rimmed, rebated rim and these categories describe the size of the rim in relation to the base of the case. The rimmed cartridge, sometimes called flanged cartridge, is the oldest of the types and has a rim that is larger in diameter than the base of the cartridge. Rimmed cartridges use the rim to hold the cartridge in the chamber of the firearm, because the rimmed cartridge headspaces on the rim, the case length is of less importance than rimless cartridges. This allows some firearms chambered for similar rimmed cartridges to safely chamber and fire shorter cartridges, rimmed cartridges are well suited to certain types of actions, such as revolvers, where the rim helps hold the cartridge in position, and break-action firearms. Semi-automatic handguns have been chambered in rimmed cartridges as well, for example a LAR Grizzly or Desert Eagle in.357 or.44 Magnum, under the metric cartridge designation system, a capitalized R added at the end of the designation denotes a rimmed cartridge. For example,7. 62×54mmR is a cartridge, while 7. 62×51mm is a rimless cartridge.45 Auto Rim. Examples of rimmed handgun cartridges include the.38 Special.357 Magnum, rimmed rifle cartridge examples include the.22 Hornet.303 British and 7. 62×54mmR. Rimless cases are not well suited to break-open and revolver actions, though they can be used with modifications, such as a spring-loaded extractor or, in a revolver. Crimping affects the length of the cartridge, and thus cannot be used on cartridges which headspace on the case mouth. Examples of rimless handgun cartridges include the 9mm Parabellum.40 S&W, rimless rifle examples include the.223 Remington.308 Winchester. 30-06 Springfield and 7. 92×57mm Mauser. On a semi-rimmed case the rim projects slightly beyond the base of the case, the tiny rim provides minimal interference feeding from a box magazine, while still providing enough surface to headspace on. Semi-rimmed cases are less common than the other types, if the chamber is cut shallow, so the case headspaces off the mouth, the rim is used for extraction only, a standard chamber will use the rim for both headspacing and extraction. Examples of more commonly encountered rimless handgun cartridges are.25 ACP.32 ACP and.38 ACP, while the.308 Marlin Express.338 Marlin Express and.444 Marlin are rifle cartridges that are semi-rimmed. Rebated rim cartridges have a rim that is smaller in diameter than the base of the case. Functionally the same as a case, the rebated rim provides some additional benefits when considered in conjunction with other cartridges. One example of a rebated rim cartridge is the.50 Action Express, by using the same rim dimensions as the.44 Magnum, a Desert Eagle could be converted from.44 Magnum to.50 AE by merely changing the barrel and magazine

Firearm
–
A firearm is a portable gun - a barreled weapon that launches one or more projectiles, often driven by the action of an explosive force. The first primitive firearms originated in 13th-century China when the fire lance was combined with projectiles. The technology gradually spread through the rest of East Asia, South Asia, older firearms typically used black powder as a propellant, but modern firearms use smokeless powder or other propellants. Most modern firearms have rifled barrels to impart spin to the projectile for improved flight stability, modern firearms can be described by their caliber or in the case of shotguns their gauge, by the type of action employed together with the usual means of deportment. The word firearms usually is used in a sense restricted to small arms, shooters aim firearms at their targets with hand-eye co-ordination, using either iron sights or optical sights. The accurate range of pistols generally does not exceed 100 yards, while most rifles are accurate to 550 yards using iron sights, some purpose-built sniper rifles are accurate to ranges of more than 2,200 yards. The smallest of all firearms is the handgun, there are three common types of handguns, single-shot pistols, revolvers, and semi-automatic pistols. Revolvers have a number of firing chambers or charge holes in a revolving cylinder, semi-automatic pistols have a single fixed firing chamber machined into the rear of the barrel, and a magazine so they can be used to fire more than one round. Each press of the fires a cartridge, using the energy of the cartridge to activate the mechanism so that the next cartridge may be fired immediately. This is opposed to double-action revolvers which accomplish the end using a mechanical action linked to the trigger pull. Prior to the 19th century, virtually all handguns were single-shot muzzleloaders, with the invention of the revolver in 1818, handguns capable of holding multiple rounds became popular. Certain designs of auto-loading pistol appeared beginning in the 1870s and had largely supplanted revolvers in military applications by the end of World War I. By the end of the 20th century, most handguns carried regularly by military, police and civilians were semi-automatic, both designs are common among civilian gun owners, depending on the owners intention. A long gun is any firearm that is larger than a handgun and is designed to be held. Early long arms, from the Renaissance up to the century, were generally smoothbore firearms that fired one or more ball shot. Most modern long guns are either rifles or shotguns, both are the successors of the musket, diverging from their parent weapon in distinct ways. A rifle is so named for the spiral fluting machined into the surface of its barrel. Shotguns are predominantly smoothbore firearms designed to fire a number of shot, shotguns are also capable of firing single slugs, or specialty rounds such as bean bags, tear gas or breaching rounds

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

Federal Bureau of Investigation
–
The Federal Bureau of Investigation is the domestic intelligence and security service of the United States, which simultaneously serves as the nations prime federal law enforcement agency. Operating under the jurisdiction of the U. S. Department of Justice, Intelligence Community and reports to both the Attorney General and the Director of National Intelligence. A leading U. S. counterterrorism, counterintelligence, and criminal investigative organization, although many of the FBIs functions are unique, its activities in support of national security are comparable to those of the British MI5 and the Russian FSB. At an FBI field office, a senior-level FBI officer concurrently serves as the representative of the Director of National Intelligence. Despite its domestic focus, the FBI also maintains a significant international footprint and these overseas offices exist primarily for the purpose of coordination with foreign security services and do not usually conduct unilateral operations in the host countries. The FBI can and does at times carry out secret activities overseas, just as the CIA has a domestic function. The FBI was established in 1908 as the Bureau of Investigation and its name was changed to the Federal Bureau of Investigation in 1935. The FBI headquarters is the J. Edgar Hoover Building, located in Washington, in the fiscal year 2012, the Bureaus total budget was approximately $8.12 billion. In 1896, the National Bureau of Criminal Identification was founded, the 1901 assassination of President William McKinley created an urgent perception that America was under threat from anarchists. The Departments of Justice and Labor had been keeping records on anarchists for years, the Justice Department had been tasked with the regulation of interstate commerce since 1887, though it lacked the staff to do so. It had made little effort to relieve its staff shortage until the breakage of the Oregon land fraud scandal at approximately the turn of the 20th Century, President Roosevelt instructed Attorney General Charles Bonaparte to organize an autonomous investigative service that would report only to the Attorney General. Bonaparte reached out to other agencies, including the Secret Service, for personnel, on May 27,1908, the Congress forbade this use of Treasury employees by the Justice Department, citing fears that the new agency would serve as a secret police department. Again at Roosevelts urging, Bonaparte moved to organize a formal Bureau of Investigation, the Bureau of Investigation was created on July 26,1908, after the Congress had adjourned for the summer. Attorney General Bonaparte, using Department of Justice expense funds, hired thirty-four people, including veterans of the Secret Service. Its first Chief was Stanley Finch, Bonaparte notified the Congress of these actions in December 1908. The bureaus first official task was visiting and making surveys of the houses of prostitution in preparation for enforcing the White Slave Traffic Act, or Mann Act, in 1932, the bureau was renamed the United States Bureau of Investigation. The following year it was linked to the Bureau of Prohibition, in the same year, its name was officially changed from the Division of Investigation to the present-day Federal Bureau of Investigation, or FBI. J. Edgar Hoover served as Director from 1924 to 1972, a combined 48 years with the BOI, DOI, Hoover was substantially involved in most major cases and projects that the FBI handled during his tenure

.45 ACP
–
The.45 ACP, or.45 Auto is a handgun cartridge designed by John Browning in 1905, for use in his prototype Colt semi-automatic pistol. After successful military trials it was adopted along with the Browning.45 Colt handgun as the.45 M1911 cartridge, the handgun was designated M1911 handgun. The U. S. Cavalry had been buying and testing various handguns in the late 1890s, the.45 Colt Single Action Army had largely been replaced, even by some double-action versions of the same caliber. The Army had fielded some double-action revolvers in.38 Long Colt and they determined the.38 caliber round was significantly less effective than the.45 Colt against determined opponents such as the Moro juramentado warriors encountered in the Moro Rebellion. This experience, and the Thompson–LaGarde Tests of 1904 led the Army and they noted, however, training was critical to make sure a soldier could score a hit in a vulnerable part of the body. The result from Colt was the Model 1905 and the new.45 ACP cartridge. The resulting. 45-caliber cartridge, named the.45 ACP, was similar in performance to the.45 Schofield cartridge, by 1906, bids from six makers were submitted, among them Brownings design, submitted by Colt. Only DWM, Savage, and Colt made the first cut, DWM, which submitted two Parabellum P08s chambered in.45 ACP, withdrew from testing after the first round of tests, for unspecified reasons. In the second round of evaluations in 1910, the Colt design passed the testing with no failures. The Colt pistol was adopted as the Model 1911, the cartridge/pistol combination was quite successful but not satisfactory for U. S. military purposes. The very first production, at Frankford Arsenal, was marked F A811, the cartridge was designed by John Browning for Colt, but the most influential person in selecting the cartridge was Army Ordnance member Gen. John T. Thompson. Thompson insisted on a real man stopper pistol, following the showing of the Armys.38 Long Colt pistols during the Philippine–American War. The.45 ACP has 1.62 ml cartridge case capacity.45 ACP maximum C. I. P. The common rifling twist rate for this cartridge is 406 mm,6 grooves, Ø lands =11.23 mm, Ø grooves =11.43 mm, land width =3.73 mm and the primer type is large pistol. The cartridge headspaces on the mouth of the case at the L3 datum reference, according to Commission Internationale Permanente pour lEpreuve des Armes à Feu Portatives rulings, the.45 ACP cartridge case can handle up to 131.000 MPa Pmax piezo pressure. In CIP-regulated countries every pistol cartridge combination has to be proofed at 130% of this maximum CIP pressure to certify for sale to consumers and this means that.45 ACP chambered arms in C. I. P. Regulated countries are proof tested at 170.30 MPa PE piezo pressure. The SAAMI pressure limit for the.45 ACP is set at 21,000 psi piezo pressure, while the SAAMI pressure limit for the.45 ACP +P is set at 23,000 psi, piezo pressure

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

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

.38 Special
–
The.38 Smith & Wesson Special is a rimmed, centerfire cartridge designed by Smith & Wesson. It is most commonly used in revolvers, although some semi-automatic pistols, in other parts of the world, it is known by its metric designation of 9×29. 5mmR or 9. 1×29mmR. Noted for its accuracy and manageable recoil, the.38 Special remains the most popular cartridge in the world more than a century after its introduction. It is used for shooting, formal target competition, personal defense. Despite its name, the caliber of the.38 Special cartridge is actually. 357–.358 inches, except for case length, the.38 Special is identical to the.38 Short Colt.38 Long Colt, and.357 Magnum. This allows the.38 Special round to be fired in revolvers chambered for the.357 Magnum. Upon its introduction, the.38 Special was originally loaded with black powder and this.38 Special variant incorporated a 200 grains round-nosed lead Lubaloy bullet, the.38 Super Police. Remington-Peters also introduced a similar loading, testing revealed that the longer, heavier 200 grains. 357-calibre bullet fired at low velocity tended to keyhole or tumble upon impact, providing more shock effect against unprotected personnel. This cartridge was called the.38 S&W Super Police or the. 38/200, britain would later adopt the. 38/200 as its standard military handgun cartridge. In 1930, Smith & Wesson introduced a large frame.38 Special revolver with a 5-inch barrel and fixed sights intended for police use, the following year, a new high-power loading called the. That same year, Colt Firearms announced that their Colt Official Police would also handle high-speed.38 Special loadings, the. 38/44 high-speed cartridge came in three bullet weights,158 grains,150 and 110 grains, with either coated lead or steel jacket, metal-piercing bullets. The media attention gathered by the. 38/44 and its ammunition eventually led Smith & Wesson to develop a new cartridge with a longer case length in 1934—this was the.357 Magnum. During World War II, some U. S. aircrew were issued.38 Special S&W Victory revolvers as sidearms in the event of a forced landing, the new military.38 Special loading propelled its 158 grains bullet at a standard 850 ft/s from a 4-inch revolver barrel. During the war, many U. S. naval and marine aircrew were also issued red-tipped.38 Special tracer rounds using either a 120 or 158 gr bullet for emergency signaling purposes. In 1956, the U. S. Air Force adopted the Cartridge, Caliber.38, Ball M41, a military variant of the.38 Special cartridge designed to conform to the rules of land warfare. By 1961, a slightly revised M41.38 cartridge specification known as the Cartridge, Caliber.38 Ball, Special, a variant of the standard M41 cartridge with a semi-pointed, unjacketed lead bullet was later adopted for CONUS police and security personnel. At the same time.38 tracer cartridges were reintroduced by the US Navy, Marines, tracer cartridges in.38 Special caliber of different colors were issued, generally as part of a standard aircrew survival vest kit. A request for more powerful.38 Special ammunition for use by Air Police and security personnel resulted in the Caliber.38 Special, Ball, in 1972, the Federal Bureau of Investigation introduced a new.38 +P loading that became known as the FBI Load

Colt Delta Elite
–
The Colt Delta Elite is a modified M1911 pistol, Series 80 configuration, chambered for the 10mm Auto. It is similar to the M1911 in design and operation, Colt manufactured both stainless steel and blued versions with eight-round magazines. A Delta Gold Cup model was offered for target competition. The stainless steel Government Model version has recently been reintroduced, the Delta Elite is credited as being the first firearm produced by a major manufacturer to chamber the 10mm. The ill-fated Bren Ten sparked a genuine interest in the 10mm round with outdoorsmen and this new generation is generally similar to the previous version. The new Delta Elites will be manufactured with the traditional barrel/bushing arrangement, Colt Customer Service stated they had a lack of acceptable accuracy problem with the bull bushingless barrel setup. That was the cause of the delay in the Delta Elites production schedule, the new Delta Elite pistol was released March 31,2009. The Delta Elite is a standard M1911 design, with a few differences from the latest Series 80 derivative of that pistol. It carries the rowel Commander type hammer of that pistol and the same features of the 1911 that have made it so popular with users. However, the Delta Elite carries a stiffer double recoil spring to handle the recoil of the 10mm round. Unlike the.400 Corbon, the 10mm can easily exceed the levels of the.357 Magnum, thus stressing the original designs limitations. Many gunsmiths have their own modifications which they feel adjust the level of felt recoil of the Delta Elite, some of the very first Delta Elites had a tendency to suffer flex-induced slide rail stress cracks. This was quickly addressed by removing the section of the rail above the slide-stop cutout, variant 1 Blued — a standard blued Delta Elite. Variant 1 Stainless — a standard stainless Delta Elite, featuring pebbled texture wrap-around grips, variant 2 — Colt Gold Cup Ten. Assembled by Colt Custom Shop with only 500 being produced, serial Numbers begin GCTEN ending with numerals from 001-500. Variant 3 — Colt Match 10, the Gold Cup versions were not available at the time, so this was the most advanced Gold Cup type available. The adjustable Millet style sight allows it to be centered for decent groups at 25 yards, according to Colt, approximately 400 were manufactured in 1988. Variant 4 — spur hammer with black grips Special variant — Colt Elite Ten Forty — the Colt Elite Ten/Forty was an edition for Lew Horton Co. in the early 1990s

The Smith & Wesson Model 4506 is a third-generation semi-automatic pistol from Smith & Wessons 4500 series of handguns. The 4506 is chambered for the.45 ACP cartridge and, with the purchase of special springs and it is constructed almost entirely from stainless steel and is thus extremely resistant to harsh weather conditions. The 4506 is a traditional double-action/single-action pistol, the first shot is fired in double-action mode. Each subsequent shot is fired single-action mode and it features one-piece Xenoy wrap-around grips with either a curved or straight back strap. The 4506 was produced from 1988 to 1999, Smith & Wesson Model 4506-1, Later, modified version of the 4506. Change to the manufacturing process. Trigger guard changed from square to round, much later, the hammer and trigger were changed to being blued instead of receiving a flash chrome finish, and the S&W roll marks were dropped in favor of laser etching. Smith & Wesson Model 4516, Compact version with a 3 3⁄4 barrel on a smaller frame accepting 7 round single column magazines, Smith & Wesson Model 4546, Double-action-only version of the 4506 with a rounded, stubby hammer. Smith & Wesson Model 4563, Midsize version with a 4 1⁄4 barrel on an alloy frame. Smith & Wesson Model 4566, Midsize version with a 4 1⁄4 barrel on a steel frame. Current issue with West Virginia State Police, in DAO, with bobbed hammer, two versions in use, Natural stainless and blackened Melonite.

Centerfire ammunition
–
A centerfire cartridge is a cartridge with a primer located in the center of the cartridge case head. Unlike rimfire cartridges, the primer is a separate and replaceable component, centerfire cartridges have supplanted the rimfire variety in all but the smallest cartridge sizes. The stronger base of a cartridge is able to withstand higher pressures which in turn give a bullet greater velocity. Larger caliber rimfire cartridges require greater volumes of priming explosive than centerfire cartridges, reducing the amount of priming explosive would reduce the reliability of rimfire cartridge ignition, and increase the probability of misfire or dud cartridges. Economies of scale are achieved through interchangeable primers for a variety of centerfire cartridge calibers. The expensive individual brass cases can be reused after replacing the primer, gunpowder, the forward portion of some empty cases can be reformed for use as obsolete or wildcat cartridges with similar base configuration. Modern cartridges larger than.22 caliber are mostly centerfire, actions suitable for larger caliber rimfire cartridges declined in popularity until the demand for them no longer exceeded manufacturing costs, and they became obsolete. An early form of ammunition, without a percussion cap, was invented between 1808 and 1812 by Jean Samuel Pauly. This was also the first fully integrated cartridge, true centerfire ammunition was invented by the Frenchman Clement Pottet in 1829. However, Pottet would not perfect his design until 1855, the centerfire cartridge was improved by Benjamin Houllier, Gastinne Renette, Charles Lancaster, George Morse, Francois Schneider, Hiram Berdan and Edward Mounier Boxer. The identifying feature of centerfire ammunition is the primer which is a cup containing a primary explosive inserted into a recess in the center of the base of the cartridge. The firearm firing pin crushes this explosive between the cup and an anvil to produce hot gas and a shower of incandescent particles to ignite the powder charge, Berdan priming is less expensive to manufacture and is much more common in military-surplus ammunition made outside the United States. Berdan primers are named after their American inventor, Hiram Berdan of New York who invented his first variation of the Berdan primer and patented it on March 20,1866, in U. S. A small copper cylinder formed the shell of the cartridge, and this system worked well, allowing the option of installing a cap just before use of the propellant-loaded cartridge as well as permitting reloading the cartridge for reuse. S. Berdan primers have remained essentially the same functionally to the present day, Berdan primers are similar to the caps used in the caplock system, being small metal cups with pressure-sensitive explosive in them. Modern Berdan primers are pressed into the pocket of a Berdan-type cartridge case. Inside the primer pocket is a bump, the anvil, that rests against the center of the cup. Berdan cases are reusable, although the process is rather involved, the used primer must be removed, usually by hydraulic pressure or a pincer or lever that pulls the primer out of the bottom

Smith & Wesson Model 4006
–
The S&W Model 4006 was a semi-automatic handgun introduced by Smith & Wesson on January 17,1990 along with the new.40 S&W cartridge. It is a 3rd-generation S&W pistol, the S&W4006 features a stainless steel frame and slide double-action with 4-inch barrel, slide-mounted de-cock/safety and an 11-round staggered-column magazine. It was one of the new 3rd-generation S&W semi-autos, designed with input from famed gunsmith Wayne Novak of Parkersburg, WV. The 4006 introduced the new.40 S&W cartridge and featured a wraparound one-piece grip made of Xenoy versus the earlier standard 2-piece grip panels, a lightweight aluminum alloy–framed S&W4003 was produced that weighed 800 grams and was more comfortable to carry. The 4046 model was a DAO pistol in all stainless steel, the first 2 digits in the model number indicate caliber. The last digit, either a 3 or 6, indicates aluminum or stainless steel frame, various safety features include a safety lever as well as a magazine safety. While a true double-action pistol, the firearm shares this magazine disconnect feature with Browning Hi-Power pistols and this feature was developed to meet the needs of various law enforcement agencies interested in providing another level of safety for their officers. California State Parks and Rec, carried the Smith & Wesson model 4006-CHP from 1996 to 2009, as the primary duty weapon issued to State Park Peace Officers. The 4006-CHP was unique in that it had a rear sight, no trigger play spring, and was engraved with the States Grizzly Bear logo. Additionally, the slide, frame, and barrel were engraved with an identification number, which started with PR. As of September 2009, both the California State Parks and Rec, Department and the Colorado State Patrol have both retired the venerable 4006 in favor of the lighter and more versatile Smith & Wesson M&P40, also chambered in.40 S&W. From possibly the mid-1990s until 2008, the Atlanta Police Department used the 4003 TSW until replacing it with the Smith & Wesson M&P, the model 4046 is issued by Brinks to its armored truck crews. The 4046 was the first semi-automatic pistol to be issued by Brinks as a duty sidearm, replacing.38 caliber Smith & Wesson revolvers. As of 2011, it was being superseded by the Smith & Wesson M&P40 in Brinks inventory, although some guards were still being issued 4046s and.38 revolvers until completion of the changeover to M&Ps

Glock Ges.m.b.H.
–
Glock Ges. m. b. H. is a weapons manufacturer headquartered in Deutsch-Wagram, Austria, named after its founder, Gaston Glock. While the company is best known for its line of polymer-framed pistols, it also produces field knives, entrenching tools, Glock handguns are used by armed forces and law enforcement organizations worldwide, including a majority of law enforcement agencies in the United States. In some countries Glock handguns are popular with citizens for personal protection, the company sponsors a competitive shooting team which travels worldwide. As of 2014, Glock produces more than two dozen models of handguns in three different sizes and seven different cartridges in three calibers, the popularity of Glock pistols can be attributed to a number of factors. They are widely reputed as highly reliable, being able to function under extreme conditions, the simplicity of the Glock design as well as its simple operating method contributes to this reliability, as it contains a relatively small number of components making maintenance and repair easier. The polymer frame makes them lighter than steel or aluminum-framed handguns. The trigger is the only operating element, all three safeties are deactivated when the trigger is pulled, and automatically activated when it is released. Glock pistols have no manual safeties, the only external controls aside from the trigger itself are the slide stop lever, the magazine catch. This adds to the simplicity of use and removes a source of error while operating the handgun under stress. Most of the components in a Glock pistol are treated with a nitriding process called Tenifer. In addition to their semi-automatic handguns, Glock also produces a pistol, the Glock 18. This model is available only to law enforcement or military organizations. Glock currently manufactures two models of knives, the Feldmesser 78 and the Feldmesser 81, the Field Knife 78 is a classic type knife, with a 165 mm blade and 290 mm overall length. The Survival Knife 81 has the overall dimensions with an additional saw on the back of the blade. The Field Knife 78 weighs 206 g and the Survival Knife 81 weighs 202 g, the grips and sheaths are made of polymer and are available in three colors, olive drab, sand, and black. As of 2016 Glock introduced a new grey color variant of Field Knife 81 and has plans to discontinue Field Knife 78 in other colors than black, Glock also produces an entrenching tool, the Feldspaten. The entrenching tool weighs 650 g and fully extended is 630 mm long, the spade and handle can be collapsed and shortened for easy transport and storage into a 260 mm ×150 mm ×60 mm package. The entrenching tool is supplied with a nylon storage/transport pouch that can be attached to a belt or backpack, Glock current international subsidiaries are, Glock America N. V. Glock, Inc

It entered Austrian military and police service by 1982 after it was the top performer on an exhaustive series of reliability and safety tests. Glocks are also popular firearms among civilians for recreational and competition shooting, home and self-defense, the companys founder, engineer Gaston Glock, had no experience with firearms design or manufacture at the time their first pistol, the Glock 17, was being prototyped. Glock introduced ferritic nitrocarburizing into the industry as an anticorrosion surface treatment for metal gun parts. In 1980, the Austrian military announced that it would seek tenders for a new, the Austrian Ministry of Defence formulated a list of 17 criteria for the new generation service pistol, The design was to be self loading. The pistol was to fire the NATO-standard 9×19 mm Parabellum round, the magazines were not to require any means of assistance for loading. The magazines were to have a capacity of eight rounds. It was to be possible to all actions one handed which are necessary to prepare the pistol for firing. The pistol was to be secure against accidental discharge from shock, strike. Disassembly of the parts for maintenance and reassembling was to be possible without the use of any tools. Maintenance and cleaning of the pistol was to be accomplished without the use of tools, the pistols construction was not to exceed 58 individual parts. Gauges, measurement tools, and precise testing devices were not to be necessary for the maintenance of the pistol. The manufacturer was to be required to provide the ministry of defence with a set of engineering drawings. These were to be supplied all the relevant details for the production of the pistol. All components were to be interchangeable between pistols. No more than 20 malfunctions were to be permitted during the first 10,000 rounds fired, after firing 15, 000-rounds of standard ammunition, the pistol was to be inspected for wear. The pistol was to then be used to fire an overpressure test cartridge generating 5,000 bar, the critical components were to continue to function properly and be up to specifications, otherwise the pistol was to be disqualified. When handled properly, under no circumstances was the user to be endangered by case ejection, the muzzle energy was to be at least 441.5 J when firing a 9×19 mm S-round/P-08 by Hirtenberger AG. Pistols scoring less than 70% of the available points were not to be considered for military use
