The Glock 32 is a compact pistol manufactured by Glock. It is a Glock 23 (pictured here) modified to fire the .357 SIGammunition. It uses a modified slide, frame, .357 SIG barrel and magazine, but is otherwise nearly identical in appearance to the Glock 23. In fact, the 23 and 32 are identical in barrel length and external dimensions, except that the 32 is slightly (10 g) heavier (probably due to its thicker barrel). Its standard magazine capacity is 13 rounds.
The difference between the Glock 32 and the Glock 32C is that the barrel and slide are ported on the C model to reduce muzzle climb while shooting the pistol.
