Remarkable for its accuracy and light recoil, the GLOCK 21SF delivers the legendary stopping power of the .45 AUTO round with 10/13 round magazine capacity. Countless law enforcement units swear by the G21SF pistol, and that's why this powerful, lightweight, all climate workhorse is standard issue from the North to South Poles. The SF model reduces the circumference of the receiver at the rear, or "back strap," offering increased comfort and controlespecially for shooters with smaller hands.

Glock 21 Capacity

Chambered in .45ACP, the Glock 21 uses a double-stack, single-feed magazine with capacities of 10 and 13 rounds.  Glock and other magazine manufacturers also offer a 26 round magazine.

Glock 21 Ergonomics

Ergonomics
The Glock 21 is a full-size pistol with a double-stack .45 caliber magazine, so the physical size of the grip may be difficult for users with smaller hands to get a full, proper grip.  However, the overall shape of the Glock 21 offers nearly the identical ergonomics of other full-size Glocks like the Glock 17.

Glock 21 Fit & Finish

The build quality of the Glock 21 is exactly what you would expect out of any Glock.  The nDLC coating is consistently applied across the slide, and the polymer frame is free of any overpress defects from the injection molding process.
Fit and Finish

Glock 21 Concealability

Concealability
With its full-size construction and boxy design, the Glock 21 would be very difficult to conceal without considerably loose fitting clothing or winter attire.  With a length over 8 inches and a height of 5.5 inches, the Glock 21 works better in an open-carry setting.
