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.
