What to Know

Critic Consensus

Recoil is very mild on the Glock G21 and pushed the gun into the web of my firing hand. The Hogue Handall grip sleeves that I installed on the gun helped in taming what recoil there is. Muzzle flip was almost negligible due to the ergonomics of the gun. I found that I could come back on target with relative ease after each shot. Read critic reviews...

Glock 21SF Description

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. This model features a threaded barrel.
