About Glock 21
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.

March 19, 2014As one of the other reviews noted, it's a big ole' Glock, what's not to like??? The order process was a little slow because I paid via E-check, but it was definitely worth the extra wait time. As for the G21SF, it arrived at my FFL free of scratches or bl
