Glock 34 Gen5 9mm with Mos-AS

The Glock 34 Gen5 is a competition version of the Glock 17. It is similar to its predecessor, the Glock 17L, but with a slightly shorter slide and barrel, to meet the maximum size requirements for many sanctioned action pistol sporting events. It was developed and produced in 1998, and compared to the Glock 17, features a 21 mm (0.8 in) longer barrel and slide. It has an extended magazine release, extended slide stop lever, 20 N trigger pull, and an adjustable rear sight. The sides at the front of the slide are slanted instead of squared. Further, the top of the slide and parts of its inside are milled out, creating a conspicuous hole at the top designed to reduce front-end muzzle weight to better balance the pistol and reduce the overall weight of the slide.
