Glock 21

Glock is a brand of polymer-framed, short-recoil-operated, locked-breech semi-automatic pistols designed and produced by Austrian manufacturer Glock GmbH. The firearm, designed by company founder Gaston Glock (1929–2023), entered Austrian military and police service in 1982 as the P80 after outperforming established competitors in reliability and safety tests. Despite initial market resistance to its "plastic" construction, the Glock became the first commercially successful line of pistols with a polymer frame.
