This Glock 34 Gen 4 MOS is a semi-automatic handgun made for competition. It is chambered in 9mm and offers maximum sight radius alongside perfect weight distribution and balance, resulting in reduced rise and felt recoil. A reversible magazine catch accommodates left- and right-handed users, while the Modular Back Strap system provides the option to customize the grips to fit any hand size. Additionally, the MOS configuration makes it easy to mount a miniature reflex sight on the slide without the need for a new slide or separate mounting system.
