The “big bore” .45 caliber belongs to the United States like stars and stripes. Americans have always had a very special relationship with this timeless caliber. The GLOCK 21 gives you everything you would expect of a ..45 pistol. Countless law enforcement units swear by this superior pistol for more than just its above-average magazine capacity of 13 rounds.
GLOCK compensator pistols are equipped with an integrated compensator, rendering the weapon even more controllable during rapid fire and allowing an improved hit pattern. The compensator consists of two longitudinal openings in the barrel and slide of the pistol arranged in "V-position". This minimizes front sight blackening through powder gases.
