The Glock 45 Gen 5 MOS Crossover combines the compact slide of the G19 with a full-size frame, offering a versatile and ergonomic design. Gen 5 enhancements include a flared Mag-well with a larger funnel for smoother reloads and the Glock Marksman Barrel (GMB) featuring aggressive polygonal rifling with a target-style crown and tighter chamber specifications for improved accuracy. Ambidextrous slide stop levers enhance ergonomics for both left-hand shooters and those using their support hand. Finger grooves have been removed for a more universal grip feel. The Safe Action System ensures that safeties disengage sequentially as the trigger is pulled and automatically re-engage upon release. An enlarged floor plate facilitates easier magazine extraction, while the customizable frame accommodates different hand sizes with two back strap options and a beavertail feature. The MOS configuration features a precision-machined slide designed for mounting popular optic sights. Multiple adapter plates (sold separately) enable quick and easy attachment of miniature red-dot sights. Each pistol includes one adapter plate, three magazines, a mag loader, cleaning kit, pistol case and gun lock, providing comprehensive functionality and accessories out of the box.
