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 control-especially for shooters with smaller hands. - 45 AUTO / Safe Action - Length: 204mm / 8.03 in. - Width: 32.50 mm / 1.27 in. - Length Between Sights: 172 mm / 6.77 in. - Height: 139 mm / 5.47 in. - Barrel Height: 32 mm / 1.26 in. - Barrel Length: 117 mm / 4.60 in. - Weights: Unloaded: 830 g / 29.30 oz.
