The G45 Modular Optic System (MOS) incorporates the popular “Crossover” design with a factory-milled slide, making it modular-optic-ready and combines the compact-size slide with the full-size frame. The G45 MOS comes with custom mounting plates to accommodate the most popular reflex optical sights.
Reflex optics (MOS) allow you to look through the reticle and focus on the target and alignment of the dot. With improved accuracy, quicker target acquisition and versatility, MOS pistols are popular in competitive shooting and are becoming increasingly popular for home defense and target shooting.
The G45 MOS incorporates the 5th Generation elements such as the ambidextrous slide- stop lever, the Modular Backstrap System, and the match-grade, GLOCK Marksman Barrel (GMB) for increased accuracy. Both the slide and barrel feature the nDLC finish, the removal of the half-moon cut seen on previous Gen5 models, and the addition of front serrations on the slide.
