G21 SF

Standard | .45 AUTO
The “big bore” 45 Auto caliber has since long been regarded with a special reverence. Many shooters feel a special relationship with this timeless caliber. The GLOCK 21SF presents everything one would expect of a 45 Auto pistol. The SF design reduces the circumference of the receiver, offering increased ease-of-use and control, especially to shooters with smaller hands.
