The Glock 18 is a fully-automatic pistol. This pistol was developed by an Austrian Glock company, headed by Gaston Glock. Some sources report that this pistol was developed to meet requirement of the EKO Cobra, an Austrian counter-terrorist unit. Other sources claim that this pistol was deigned to increase appeal of the gun to military and police markets. It is worth noting that in the 1980s weapons produced by Glock were little known and very unusual.
The Glock 18 is chambered for 9x19 mm Parabellum round. This pistol has high muzzle energy and provides good penetration, even with 9x19 mm ammunition. Cyclic rate of fire is a whooping 1200 rounds per minute.
The Glock 18 is fed by a double-stack magazine that holds 17 rounds. The magazine is interchangeable with the Glock 17. Also this pistol can be fed from a 31- or 33-round magazine. The rate of fire is that high, that you can empty the 33-round magazine in less than two seconds.
