The .40 caliber introduced at the 1990 S.H.O.T. Show closes the gap between the heavy .45 charges and the internationally proven 9 x 19mm service calibers. GLOCK was the first manufacturer to make the advantages of this balanced caliber accessible to law enforcement agencies in a perfect pistol. Today, countless police units in the United States and throughout the world put their trust in the 15-round GLOCK 22.
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.
