The Glock is a series of hammerless semi-automatic pistols designed by Gaston Glock, an Austrian gunsmith.
Glocks come in many sizes and calibers, from 9mm Parabellum to .357 SIG. Many police departments use the Glock as their standard handgun to replace more heavier all-metal handguns. It is also one of the most common handguns in the United States making it almost no problem to find one. Some are small enough to be suitable for concealed carry. However problems are still visible. On the barrel where the cartridge is supported in the chamber, the round is not fully supported or surrounded (near and around the head of the cartridge, particularly the bottom). And that can cause a blowup of the gun. That can cause injuries of hands, even using factory rounds.
The Austrian military made a request for a new service pistol in 1980. The Ministry of Defence formed a list of 17 criteria for the pistol. Glock became aware of the request, and in 1982, assembled a team of Europe's leading handgun experts to help with the design and construction of a new handgun. Several prototypes of the Glock 17, so named as it was the 17th set of technical drawings in the design, were submitted for trials in early 1982, and after passing all of the endurance and stress tests, the Glock 17 was announced as the new service pistol for the Austrian military. It was adopted into military and police service under the designation Pistole 80, or P80, and 25,000 handguns were shipped out.
The pistol is very common among police and military services across the globe, with some examples being the Los Angeles Police Department, Australian Federal Police, the 601st Special Forces Group of the Czech Army, the Hong Kong Police, the Latvian military, the Metropolitan Police Service of London, the FBI, DEA and the Department of Homeland Security. There are models chambered for 9mm, .45 ACP and .45 GAP (Glock Automatic Pistol), 10mm Auto, .357 SIG, .380 ACP and .40 S&W. It is a popular weapon among civilian shooters worldwide, too. The Glock line of pistols is renowned for reliability and accuracy.
