GLOCK 21 Gen 4 .45 ACP

The Glock 21 Gen 4, like any other Glock, is known for it’s lightweight yet packing a punch. Bringing the legendary stopping power of the classic .45 AUTO round while being light on the hip. The Frame is as compact as possible with its Small Frame technology, all whilst keeping the 10 round capacity in the double stack magazine.

Adapt your gun to your palm size with the Gen 4 Modular back strap system. Left Handed? You’re able to reverse the magazine release on this to accommodate you whether being left or right handed. The Rough textured Stippling will make sure you keep a positive grip on the pistol. Don’t worry about being a .45 AUTO round with a polymer pistol as the Gen 4 line features their new dual recoil spring assembly which outlasts their previous recoil assembly and extends operation.
