GLOCK 21 SF .45 ACP Small Frame

The Glock 21 SF is remarkable for its accuracy and light felt recoil despite being a polymer frame. Backed with the stopping power of the classic .45 AUTO Round which makes it the trust side arm of countless US Law enforcement alike. The “SF” Stands for Small Frame, making this large round more manageable by those with smaller hands giving the power back to the shooter.
