Glock 19: Effectively, a reduced-size Glock 17, called the “Compact” by the manufacturer. It was first produced in 1988, primarily for military and law enforcement. The Glock 19 has a barrel and pistol grip that are shorter by approx. 12 mm (0.5 in) compared to the Glock 17 and uses a 15-round magazine (the pistol remains compatible with standard and high-capacity factory magazines). To preserve the operational reliability of the short recoil system, the slide's mass was kept the same. With the exception of the slide, frame, barrel, locking block, recoil spring, guide rod and slide lock spring, all of the other components are interchangeable between the models 17 and 19. In 1990 the Glock 19 was accepted by the Swedish Army and entered service as the Pistol 88B.
