The 9×19mm Parabellum (also known as 9mm Luger, 9mm NATO or simply 9mm) is a Rim (firearms)#Rimless, rimless, Centerfire ammunition, centerfire, tapered cartridge (firearms), firearms cartridge. Originally designed by Austrian firearm designer Georg Luger in 1901, it is widely considered the most popular handgun and submachine gun cartridge due to its low cost, adequate stopping power and extensive availability. Since the cartridge was designed for the Luger pistol, Luger semi-automatic pistol, it has been given the designation of ''9mm Luger'' by the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) and the (CIP). A 2007 US survey concluded that "about 60 percent of the firearms in use by police are 9mm [Parabellum]" and credited 9×19mm Parabellum pistol sales with making semiautomatic pistols more popular than revolvers.Adler, Jerry, et al.

Beretta Model 92
The Beretta 92 (also Beretta 96 and Beretta 98) is a series of semi-automatic pistols designed and manufactured by Beretta of Italy. History Carlo Beretta, Giuseppe Mazzetti and Vittorio Valle, all experienced firearms designers, contributed to the final design in 1975. The Beretta 92 was designed in 1975, and production began in 1976. Many variants in several calibers continue to be used to the present. Evolution 92 Production began in May 1976, and ended in February 1983. Approximately 7,000 units were of the first "step slide" design and 45,000 were of the second "straight slide" type. 92S In order to meet the requirements of some law enforcement agencies, Beretta modified the Beretta 92 by adding a slide-mounted combined safety and decocking lever, replacing the frame-mounted manual thumb safety.

Beretta M9
The Beretta M9, officially the Pistol, Semiautomatic, 9mm, M9, is the designation for the Beretta 92FS semi-automatic pistol used by the United States Armed Forces. The M9 was adopted by the United States military as their service pistol in 1985. The 92FS won a competition in the 1980s to replace the M1911A1 as the primary sidearm of the U.S. military, beating many other contenders and only narrowly defeating the SIG Sauer P226 for cost reasons. It officially entered service in 1990. Some other pistols have been adopted to a lesser extent, namely the SIG P228 pistol, and other models remain in limited use. The M9 was scheduled to be replaced under a United States Army program, the ''Future Handgun System'' (FHS), which was merged with the ''SOF Combat Pistol'' program to create the '' Joint Combat Pistol'' (JCP). The JCP was renamed ''Combat Pistol'' (CP), and the number of pistols to be bought was drastically cut back. The U.S. Army, Navy, Air Force, and Marine Corps are ...

Smith & Wesson Model 39
The Smith & Wesson Model 39 is a semiautomatic pistol developed for the United States Army service pistol trials of 1954. After the Army abandoned its search for a new pistol, the Model 39 went on the civilian market in 1955 and was the first of Smith & Wesson's first generation semi-automatic pistols. A modified version saw limited use with Naval Special Warfare units as the Mk 22 Mod 0. History During World War II, the German Walther P38 double-action/single-action pistol impressed American ordnance personnel so much that the Army Ordnance Corps issued a proposal for an American equivalent to the P38.

Submachine Gun
A submachine gun (SMG) is a magazine (firearms), magazine-fed automatic firearm, automatic carbine designed to fire handgun cartridges. The term "submachine gun" was coined by John T. Thompson, the inventor of the Thompson submachine gun, to describe its design concept as an automatic firearm with notably less firepower than a machine gun (hence the prefix "wikt:sub-, sub-"). As a machine gun must fire rifle cartridges to be classified as such, submachine guns are not considered machine guns. The submachine gun was developed during World War I (1914–1918) as a Close-quarters battle, close quarter offensive weapon, mainly for trench raiding. At its peak during World War II (1939–1945), millions of submachine guns were made for shock troops, assault troops and auxiliaries whose military doctrine, doctrines emphasized close-quarters combat, close-quarter suppressive fire. New submachine gun designs appeared frequently during the Cold War,Military Small Arms Of The 20th Century. Ian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Semi-automatic Pistol
A semi-automatic pistol (also called a self-loading pistol, autopistol, or autoloading pistol) is a repeating firearm, repeating handgun that automatically ejects and loads cartridge (firearms), cartridges in its chamber (firearms), chamber after every shot fired, but only one round of ammunition is fired each time the Trigger (firearms), trigger is pulled. The pistol's fire control group disconnects the trigger mechanism from the firing pin/striker until the trigger has been released and reset manually, unlike the self-cycled firing mechanism in machine pistol, fully automatic pistols. A semi-automatic pistol recycles part of the energy released by the propellant combustion to move its bolt (firearm), bolt, which is usually housed inside the pistol slide, slide. After a round of ammunition is fired, the spent cartridge casing is extracted and ejected as the slide/bolt moves rearwards under recoil, the hammer (firearms), hammer/striker is cocked by the slide/bolt movement, and a ...

Si Vis Pacem, Para Bellum
() is a Latin adage translated as "If you want peace, prepare for war." The phrase is adapted from a statement found in Roman author Publius Flavius Vegetius Renatus's tract ''De Re Militari, Dē Rē Mīlitārī'' (fourth or fifth century AD), in which the actual phrasing is ''Igitur quī dēsīderat pācem, præparet bellum'' ("Therefore let him who desires peace prepare for war"). The idea which it conveys also appears in earlier works such as Plato's ''Nomoi'' (''Laws (dialogue), Laws''). The phrase presents the insight that the conditions of peace are often preserved by a readiness to make war to defend said peace when the need arises. Derived uses Whatever the source, the adage has become a living vocabulary item itself, used in the production of different ideas in a number of languages. For example, in 1790 during his first annual address to a joint session of United States Congress, Congress, George Washington stated "To be prepared for war is one of the most effectua ...

Deutsche Waffen- Und Munitionsfabriken
''Deutsche Waffen- und Munitionsfabriken Aktiengesellschaft'' (German Weapons and Munitions public limited company), known as DWM, was an arms company in Imperial Germany created in 1896 when ''Ludwig Loewe & Company'' united its weapons and ammunition production facilities within one company. In 1896 Loewe founded Deutsche Waffen- und Munitionsfabriken with a munitions plant in Karlsruhe (Baden), formerly Deutsche Metallpatronenfabrik Lorenz, and the weapons plant in Berlin. Shares that Loewe had in other gun- and ammunition plants were transferred to DWM. This included Waffenfabrik Mauser, Fabrique Nationale d'Armes de Guerre (FN) in Belgium and Waffen- und Munitionsfabrik A.G. in Budapest.

Sintering
Sintering or frittage is the process of compacting and forming a solid mass of material by pressure or heat without melting it to the point of liquefaction. Sintering happens as part of a manufacturing process used with metals, ceramics, plastics, and other materials. The atoms/molecules in the sintered material diffuse across the boundaries of the particles, fusing the particles together and creating a solid piece. Since the sintering temperature does not have to reach the melting point of the material, sintering is often chosen as the shaping process for materials with extremely high melting points, such as tungsten and molybdenum. The study of sintering in metallurgy, metallurgical powder-related processes is known as powder metallurgy. An example of sintering can be observed when ice cubes in a glass of water adhere to each other, which is driven by the temperature difference between the water and the ice. Examples of pressure-driven sintering are the compacting of snowfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
