Semi-automatic Pistol
A semi-automatic pistol (sometimes ''automatic pistol'') is a handgun that automatically ejects and loads cartridges in its chamber after every shot fired. Only one round of ammunition is fired each time the trigger is pulled, as the pistol's fire control group disconnects the trigger mechanism from the firing pin/striker until the trigger has been released and reset. Additional terms sometimes used as synonyms for a semi-automatic pistol are self-loading pistol, autopistol, autoloading pistol, and automatic pistol. A semi-automatic pistol recycles part of the energy released by the propellant combustion to move its bolt, which is usually housed inside the 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/striker is cocked by the slide/bolt movement, and a new round from the magazine is pushed into the chamber when the slide/bolt returns forward under spring tension.

Glock 22 Surrounded By
Glock is a brand of polymer- framed, short recoil-operated, locked-breech semi-automatic pistols designed and produced by Austrian manufacturer Glock Ges.m.b.H. The firearm entered Austrian military and police service by 1982 after it was the top performer in reliability and safety tests. Glock pistols have become the company's most profitable line of products, and have been supplied to national armed forces, security agencies, and police forces in at least 48 countries. Glocks are also popular firearms among civilians for recreational and competition shooting, home- and self-defense, both in concealed or open carry. In 2020, the Glock 19 was the best selling pistol on GunBroker. History The company's founder, head engineer Gaston Glock, had no experience with firearms design or manufacture at the time their first pistol, the Glock 17, was being prototyped. Glock had extensive experience in advanced synthetic polymers, which was instrumental in the company's design of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gas-operated Reloading
Gas-operation is a system of operation used to provide energy to operate locked breech, autoloading firearms. In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to dispose of the spent case and insert a new cartridge into the chamber. Energy from the gas is harnessed through either a port in the barrel or a trap at the muzzle. This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the action, extraction of the spent case, ejection, cocking of the hammer or striker, chambering of a fresh cartridge, and locking of the action. History The first mention of using a gas piston in a single-shot breech-loading rifle comes from 1856, by the German Edward Lindner who patented his invention in the United States and Britain. In 1866, Englishman William Curtis filed the first patent on a gas-operated repeating rifle, but subsequently failed to develop that idea further. Between 18 ...

M1911 Pistol
The M1911 (Colt 1911 or Colt Government) is a single-action, recoil-operated, semi-automatic pistol chambered for the .45 ACP cartridge. The pistol's formal U.S. military designation as of 1940 was ''Automatic Pistol, Caliber .45, M1911'' for the original model adopted in March 1911, and ''Automatic Pistol, Caliber .45, M1911A1'' for the improved M1911A1 model which entered service in 1926. The designation changed to ''Pistol, Caliber .45, Automatic, M1911A1'' in the Vietnam War era. Designed by John Browning, the M1911 is the best-known of his designs to use the short recoil principle in its basic design. The pistol was widely copied, and this operating system rose to become the preeminent type of the 20th century and of nearly all modern centerfire pistols. It is popular with civilian shooters in competitive events such as the International Defensive Pistol Association and International Practical Shooting Confederation. The U.S. military procured around 2.7 million M1911 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beretta 92
The Beretta 92 (also Beretta 96 and Beretta 98) is a series of semi-automatic pistols designed and manufactured by Beretta of Italy. The Beretta 92 was designed in 1975, and production began in 1976. Many variants in several different calibers continue to be used to the present. The United States military replaced the .45 ACP M1911A1 pistol in 1985 with the Beretta 92FS, designated as the " M9." History The Beretta 92 pistol evolved from earlier Beretta designs, most notably the M1923 and M1951. From the M1923 comes the open slide design, while the alloy frame and locking block barrel, originally from Walther P38, were first used in the M1951. The grip angle and the front sight integrated with the slide were also common to earlier Beretta pistols. What were perhaps the Model 92's two most important advanced design features had first appeared on its immediate predecessor, the 1974 .380 caliber Model 84. These improvements both involved the magazine, which featured direct feed; ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
