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

Ruger and Alexander McCormick Sturm in 1949 in a small rented shop in Southport. Ruger is a dominant manufacturer in the.22 LR rimfire rifle market in the U. S. due primarily to the sales of its Ruger 10/22 semiautomatic rifle, the 10/22 is very popular due to being relatively inexpensive and of good quality. As a result, a wealth of after-market accessories and parts were available for it. The availability and variety of after-market parts makes it possible to build a 10/22 using only these parts, Ruger similarly dominates the.22 rimfire semi-automatic pistol market with the Ruger MK II and Ruger MK III, descendants of the Ruger Standard pistol. Like the 10/22, the MkII is supported with a variety of after-market accessories. The 22/45 is similar to the Ruger Standard family of pistols but features a different grip angle, Ruger Casting has plants in Newport, New Hampshire and Prescott, Arizona, making ferrous, ductile iron and commercial titanium castings. Ruger Golf makes steel and titanium castings for golf clubs made by a number of different brands, Sturm, Ruger stock has been publicly traded since 1969, and became a New York Stock Exchange company in 1990. After Alex Sturm’s death in 1951, William B, Ruger continued to direct the company until his death in 2002. From 1949 through 2004, Ruger manufactured over 20 million firearms, and currently offers models for hunting, target shooting, self-defense, collecting, and law enforcement.

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.

.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

.357 Magnum
–
The.357 S&W Magnum, or simply.357 Magnum, is a revolver cartridge with a. 357-inch bullet diameter. It was created by Elmer Keith, Phillip B, Wesson of firearms manufacturers Smith & Wesson and Winchester. It is based upon Smith & Wessons earlier.38 Special cartridge, the.357 Magnum cartridge was introduced in 1934, and its use has since become widespread. This cartridge started the Magnum era of handgun ammunition, the.357 Magnum cartridge is notable for its stopping power. The.357 Magnum was collaboratively developed over a period in the early to mid-1930s by a group of individuals in a response to Colts.38 Super Automatic. Tests at the revealed that those vests defeated any handgun cartridge traveling at less than about 1,000 feet per second. Colts.38 Super Automatic just edged over that velocity and was able to penetrate car doors and vests that bootleggers and gangsters were employing as cover. Though.38 and.357 would seem to be different diameter chamberings, they are in fact identical, the.38 Special nomenclature relates to the previous use of heeled bullets, which were the same diameter as the case. Thus, the only difference in the two cartridges is a slight difference in length, solely for safety purposes. Much credit for the. 357s early development is given to hunter and experimenter Elmer Keith, the. 38-44 HV load used the. 38-Special cartridge loaded to a much higher velocity than standard. 38-Special ammunition. The. 38-44 revolvers were made by using a.44 Special size gun with the barrel bored to accept. 357-caliber bullets, since the frame, cylinder, and barrel were much stronger than the standard.38 Special components, it was capable of withstanding much higher pressures. The. 38-44 HV round, while no longer available, was in most cases the equal of the later.357 Magnum, which works at more than double the pressure of standard.38 Special. Elmer Keith also contributed the Keith-style bullet, which increased the mass of bullet located outside the cartridge, the Keith bullet also employed a large, flat meplat, thus enabling rapid energy transfer for greater wounding properties. At the same time, this design does not deform like a hollow point. These characteristics of the Keith bullet make it suitable for hunting applications as well as for target shooting. In order to reassert itself as the leading law-enforcement armament provider, Smith & Wesson developed the.357 Magnum, Wesson leading the effort within Smith & Wesson, along with considerable technical assistance from Phillip B. Sharpe, a member of the Technical Division staff of the National Rifle Association, the new round was developed from Smith & Wessons existing.38 Special round. It used a different powder load, and ultimately the case was extended by 1⁄8 inch, the case extension was more a matter of safety than of necessity

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

Service pistol
–
A service pistol is any handgun issued to military personnel or law enforcement officers. Pistols are not typically issued to front-line infantry, before firearms were commonplace, officers typically carried swords instead. Traditionally, soldiers and officers had carried swords for both protection and use in combat. Training was also a factor—it took a long time to train new recruits in the use of longbows. As a result, swords were retained only by officers and by cavalry, the invention of the revolver in 1836 finally made a service pistol practical, as prior to this pistols had largely been single-shot weapons usually of no particular standardized pattern. Although officers traditionally had been obligated to buy their own weapons, non-commissioned officers, service pistols, on the other hand, were generally issued to officers, NCO, and others who needed to carry personal weapons as part of their duties. Hence, it was common for officers to carry government-issued service pistols in combat. Special operations soldiers often carry a handgun as a weapon to serve in a supplementary capacity to their primary weapon. Soldiers who do not serve in a combat role are often issued a pistol. Service pistols are issued to police and other soldiers acting in a law enforcement capacity as part of their duties. The tradition of issuing pistols to officers as a weapon is being phased out by many nations. The United States Marine Corps, for example, recently began requiring all enlisted personnel and all officers below the rank of Lieutenant Colonel to carry the M4 Carbine as their primary weapon

Colt's Manufacturing Company
–
Colts Manufacturing Company is an American firearms manufacturer, founded in 1855 by Samuel Colt. It is the corporation to Colts earlier firearms-making efforts, which started in 1836. Colts earliest designs played a role in the popularization of the revolver. Although Samuel Colt did not invent the concept, his designs resulted in the first very successful ones. The most famous Colt products include the Colt Walker, made 1847 in the facilities of Eli Whitney Jr. Though they did not develop it, for a long time Colt was also responsible for all AR-15 and M16 rifle production. The most successful and famous of these are numerous M16 carbines, including the Colt Commando family, in 2002, Colt Defense was split off from Colts Manufacturing Company. Colts Manufacturing Company now serves the market, while Colt Defense serves the law enforcement, military. The two companies remained in the same West Hartford, Connecticut location cross-licensing certain merchandise before reuniting in 2013, following the loss of its M4 contract in 2013, Colt was briefly in Chapter 11 Bankruptcy, starting in 2015. Samuel Colt received a British patent on his design for a revolver in 1835. That same year, he founded his first corporation for its manufacture, the first firearm manufactured at the new Paterson plant, however, was the Colt First Model Ring Lever rifle beginning in 1837. This was followed thereafter in late 1837 by the introduction of the Colt Paterson. This corporation suffered quality problems in production, making firearms with interchangeable parts was still rather new, and it was not yet easy to replicate across different factories. Interchangeability was not complete in the Paterson works, and traditional gunsmithing techniques did not fill the gap entirely there, the Colt Paterson revolver found patchy success and failure, some worked well, while others had problems. The United States Marine Corps and United States Army reported quality problems with these earliest Colt revolvers, production had ended at the New Jersey corporation by 1842. Colt made another attempt at revolver production in 1846 and submitted a prototype to the US government, during the Mexican–American War, this prototype was seen by Captain Samuel Hamilton Walker who made some suggestions to Colt about making it in a larger caliber. Having no factory or machinery to produce the pistols, Samuel Colt collaborated with the Whitney armory of Whitneyville and this armory was run by the family of Eli Whitney. Eli Whitney Jr, the son of the patriarch, was the head of the family armory

Colt Single Action Army
–
The Colt SAA has been offered in over 30 different calibers and various barrel lengths. Its overall appearance has remained consistent since 1873, Colt has discontinued its production twice, but brought it back due to popular demand. The revolver was popular with ranchers, lawmen, and outlaws alike and its design has influenced the production of numerous other models from other companies. The Colt SAA revolver is a piece of Americana, known as The Gun That Won the West. For the design, Colt turned to two of its best engineers, William Mason and Charles Brinckerhoff Richards who had developed a number of revolvers and black powder conversions for the company. Their effort was designed for the United States government service revolver trials of 1872 by Colts Patent Firearms Manufacturing Company, production began in 1873 with the Single Action Army model 1873, also referred to as the New Model Army Metallic Cartridge Revolving Pistol. The very first production Single Action Army, serial number 1, thought lost for years after its production, was found in a barn in Nashua. It was chambered in.45 Colt, a centerfire design containing charges of up to 40 grains of fine-grained black powder, relative to period cartridges and most later handgun rounds, it was quite powerful in its full loading. The Colt Single Action Army revolver, along with the 1870 and 1875 Smith & Wesson Model 3 Schofield revolver, the Colt.45 is a famous piece of American history, known as The Gun That Won the West. The Single Action Army became available in barrel lengths of 4¾, 5½ as well as the Cavalry standard. The shorter barrelled revolvers are sometimes called the Civilian or Gunfighter model, there was also a variant with a sub 4 barrel, without an ejector rod unofficially referred to as the Sheriffs Model, Bankers Special, or Storekeeper. From 1875 until 1880 Colt marketed a single-action revolver in.44 rimfire Henry caliber in a number range from no.1 to 1,863. A Flattop Target Model was listed in Colts catalogs from 1890 to 1898, Colt manufactured 914 of these revolvers with a frame which was flat on top and fitted with an adjustable leaf rear sight. The front sight consisted of a base with an interchangeable blade, in 1920, larger, highly visible sights replaced the original thin blade and notch. The revolvers remained essentially unchanged from that point until cessation of manufacture at the beginning of World War II, from 1873 through 1940, production of the Colt Single Action Army reached 357,859. This is identified as the Pre War or First Generation of the model, calibers, at least thirty in all, ranged from.22 rimfire through.476 Eley, with approximately half, or 158,884, chambered for.45 Colt. The next most prevalent were the. 44-40 Winchester Center fire at 71,392, 38-40 at 50,520, 32-20 Winchester at 43,284 and, the 41 Colt at 19,676. All original, good condition, U. S. Cavalry and Artillery Single Action Armies are among the most valuable to collectors, especially valuable, often going for well over $10,000, are the OWA and the rare Henry Nettleton inspected Single Action Army Colts

Investment casting
–
Investment casting is an industrial process based on lost-wax casting, one of the oldest known metal-forming techniques. The term lost-wax casting can also refer to modern investment casting processes, Investment casting has been used in various forms for the last 5,000 years. In its earliest forms, beeswax was used to form necessary for the casting process. Today, more advanced waxes, refractory materials and specialist alloys are used for making patterns. Investment casting is valued for its ability to produce components with accuracy, repeatability, versatility and integrity in a variety of metals, the fragile wax patterns must withstand forces encountered during the mold making. Much of the wax used in investment casting can be reclaimed and reused, lost-foam casting is a modern form of investment casting that eliminates certain steps in the process. Investment casting derives its name from the pattern being invested with a refractory material, many materials are suitable for investment casting, examples are stainless steel alloys, brass, aluminium, carbon steel and glass. The material is poured into a cavity in a material that is an exact duplicate of the desired part. Due to the hardness of materials used, investment casting can produce products with exceptional surface qualities. The process can be used for small castings of a few ounces and large castings weighing several hundred pounds. It can be more expensive than die casting or sand casting, Investment casting can produce complicated shapes that would be difficult or impossible with other casting methods. It can also produce products with exceptional qualities and low tolerances with minimal surface finishing or machining required. Castings can be made from a wax model or from wax replicas of an original pattern that need not be made from wax. The following steps describe the process, which can take two to seven days to complete. Produce a master pattern, An artist or mould-maker creates a pattern from wax, clay, wood, plastic. Create a mould, A mould, known as the die, is made to fit the master pattern. If the master pattern was made from steel, the die can be cast directly from the pattern using metal with a lower melting point. Rubber moulds can also be cast directly from the master pattern, alternatively, a master die can be machined independently—without creating a master pattern

United States Postal Service
–
The United States Postal Service, is an independent agency of the United States federal government responsible for providing postal service in the United States. It is one of the few government agencies explicitly authorized by the United States Constitution, Mail traces its roots to 1775 during the Second Continental Congress, where Benjamin Franklin was appointed the first postmaster general. The USPS as of February 2015 has 617,254 active employees, the USPS is the operator of the largest civilian vehicle fleet in the world. The USPS is legally obligated to serve all Americans, regardless of geography, at uniform price, the USPS has exclusive access to letter boxes marked U. S. The USPS lost $5.5 billion in fiscal year 2014 and $5.1 billion in 2015, in the early years of the North American colonies, many attempts were made to initiate a postal service. These early attempts were of small scale and usually involved a colony, Massachusetts Bay Colony for example, for example, informal independently-run postal routes operated in Boston as early as 1639, with a Boston to New York City service starting in 1672. A central postal organization came to the colonies in 1691, when Thomas Neale received a 21-year grant from the British Crown for a North American Postal Service, the patent included the exclusive right to establish and collect a formal postal tax on official documents of all kinds. The tax was repealed a year later, Neale appointed Andrew Hamilton, Governor of New Jersey, as his deputy postmaster. The first postal service in America commenced in February 1692, rates of postage were fixed and authorized, and measures were taken to establish a post office in each town in Virginia. Massachusetts and the other colonies soon passed laws, and a very imperfect post office system was established. Neales patent expired in 1710, when Parliament extended the English postal system to the colonies, the chief office was established in New York City, where letters were conveyed by regular packets across the Atlantic. Before the Revolution, there was only a trickle of business or governmental correspondence between the colonies, most of the mail went back and forth to counting houses and government offices in London. The Revolution made Philadelphia, the seat of the Continental Congress, News, new laws, political intelligence, and military orders circulated with a new urgency, and a postal system was necessary. Journalists took the lead, securing post office legislation that allowed them to reach their subscribers at very low cost, overthrowing the London-oriented imperial postal service in 1774-1775, printers enlisted merchants and the new political leadership, and created a new postal system. The United States Post Office was created on July 26,1775, the official post office was created in 1792 as the Post Office Department. It was based on the Constitutional authority empowering Congress To establish post offices, the 1792 law provided for a greatly expanded postal network, and served editors by charging newspapers an extremely low rate. The law guaranteed the sanctity of personal correspondence, and provided the country with low-cost access to information on public affairs. Rufus Easton was appointed by Thomas Jefferson first postmaster of St. Louis under the recommendation of Postmaster General Gideon Granger, Rufus Easton was the first postmaster and built the first post office west of the Mississippi
