The Glock 21 is a 45 ACP caliber pistol that Glock introduced in the 1988. It was designed to target the American market, especially U.S. law enforcement. Built on a similar frame as the related Glock 20, the G-21 is larger than the ever popular Glock 17.
Carrying 13 rounds of .45 ACP ammunition, the Glock 21 became popular with law enforcement agencies who were transitioning to the more potent .45 round.
From a holster perspective, gun holsters for the Glock 21 will also fit the Glock 20 and vice versa.
