Glock 21

Remarkable for its accuracy and light recoil, the GLOCK 21 delivers the legendary stopping power of the .45 AUTO round with a 10/13 round magazine capacity. Countless law enforcement units swear by the G21 pistol, and that’s why this powerful, lightweight, all climate workhorse is standard issue from the North to South Poles.

Glock pistols chambered for the .45 ACP feature octagonal polygonal rifling rather than the hexagonal shaped bores used for models in most other chamberings. Octagonal rifling provides a better gas seal in relatively large diameter rifled bores, since an octagon resembles a circle more closely than a hexagon.

The Glock 21 is a .45 ACP version of the Glock 20 designed primarily for the American market. Compared to the Glock 20 chambered in 10mm Auto, the slide of the Glock 21 is lighter to compensate for the lower-energy .45 ACP cartridge. The standard Glock 21 magazine is of the single-position-feed, staggered-column type with a capacity of 13 rounds.

The Glock 21SF is a version of the Glock 21 that utilizes the Short Frame (SF) which is based on the standard G21 frame (same width), but reduces the trigger reach from the back of the grip by 2.5 mm (0.098 in) and the heel of the pistol is shortened by 4 mm (0.16 in) so the trigger can be reached and operated better by users with relatively small hands.
