The history of semi-automatic pistol

/kloc-In the late 20th century, the appearance of smokeless gunpowder and metal shell bullets made it possible to shoot guns repeatedly. After Ma Keqin invented the machine gun that used recoil to finish the process of shell unloading, loading and firing, he began to apply this principle to rifles, but the pistol design was still relatively backward. 1892, the Austrian first developed the 8mm Schoenberg pistol, which is recognized as the first self-loading pistol in the world. In early semi-automatic pistol, fixed magazines or magazines similar to revolvers were used for ammunition supply, so there was not much advantage at that time.

1898, Georg Ruger improved the detachable magazine of C93 semi-automatic pistol, which was designed in cooperation with borchardt and did not need the balancing device like the early automatic pistol. As a result, it became a German and multinational pistol, namely Luger P08, which became a new indicator of semi-automatic pistol. 1900, Browning invented the semi-automatic pistol with a sleeve (carriage) loading system, which solved the security problems caused by the inconvenient loading in early semi-automatic pistol. He and Colt cooperated with Fabrique Nationale for a long time, including Browning M 1903 and Colt M1910, which were later adopted as standard pistols by many countries.

During World War I, semi-automatic pistol was used by many participating countries, because the detachable magazine design can ensure the cleanliness of bullets, which is far better than the magazine clip of fixed magazine, and the advantages of magazine capacity and firing rate are also better than that of revolver pistol. Before World War II, Germany equipped Walter P38 with double triggers, which solved the problem that Ruger P08 was easy to go off. Browning also designed the first double-row magazine and a more effective locking mechanism, namely the famous Browning powerful pistol.

During World War II, the pistol itself made little progress, and submachine guns became the main weapons in melee. In order to use ammunition, most countries use semi-automatic pistol as standard equipment. After World War II, due to the establishment of the two military alliance systems of NATO and Warsaw Pact, the caliber of standard pistol bullets tends to be unified, and NATO's United States and a few European and American countries use 45 ACP and 9 mm Luger bullets. On the other hand, Kazuki Watanabe musician used the pre-war 7.62mm tokarev and the newly designed 9mm makarov bomb in 1950s.

Since 1970s, many new pistols have Browning and Walter insurance institutions at the same time. As an Austrian pistol, Glock adopted a lot of engineering plastics and safe maneuvering technology on the surface of ordinary pistols, which effectively reduced the number of parts and improved the safety. In order to solve the problem of firing supersonic bullets, designers began to use high-strength alloy steel to manufacture parts. So in the 1980s and 1990s, semi-automatic pistol was introduced, such as the famous Israeli desert eagle, which can fire medium and large caliber supersonic Ma Genan bullets, and Fabrique Nationale even introduced a 57 pistol with a high muzzle velocity of 5.7x28 bullets. At the same time, semi-automatic pistol has become the mainstream pistol of the army and police.
