GLOCK 17

The Glock 17 is an Austrian double-action only (DAO) semi-automatic pistol which first appeared in 1983 supplying the Austrian army, and then became popular around the world particularly with American police forces. It is a self-cocking automatic pistol using a locked breech relying on the Browning tilting barrel, and produced in 40 per cent plastic materials. The Glock 17 is chambered for the 9 mm Parabellum cartridge and takes a 17 round magazine. A variant, the Glock 17L is a longer model with a 153 mm long barrel, rather than a 114 mm long barrel as fitted to the standard model.
