GLOCK introduced the G22 .40 in 1990 and effectively closed the gap between the heavy .45 Auto, and the internationally proven 9x19. GLOCK was the first manufacturer to make this popular and effective round accessible for law enforcement agencies. Today, police agencies across the U.S., and countless others throughout the world, put their trust in this 15-round .40 caliber pistol. Each pistol is delivered only after passing stringent quality inspections, exhaustive quality control checks, and test firing in the factory.
