A semi-automatic handgun made for competition, this Glock G41 Gen 4 MOS offers maximum sight radius while achieving perfect weight distribution and balance, which, in turn, reduces muzzle rise and felt recoil. This pistol is chambered in 45 ACP and sports a reversible magazine catch to accommodate both 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.
