The Glock 45 Gen 5 Crossover combines a compact slide with a full-size frame, providing a versatile firearm platform. It incorporates several Gen 5 enhancements: a flared Mag-well with a larger funnel for smoother magazine changes and a Glock Marksman Barrel (GMB) featuring aggressive polygonal rifling and a target-style crown for improved accuracy. The ambidextrous slide stop levers enhance ergonomics for left-handed shooters and support-hand operation. Gen 5 improvements also include the removal of finger grooves for a more adaptable grip. The Safe Action System ensures that safeties disengage sequentially as the trigger is pulled and automatically re-engage upon trigger release. An enlarged floor plate facilitates easier magazine extraction, while the customizable frame size with two back strap options, including one with a beavertail, allows users to adjust the grip circumference to fit their hand size precisely. Each Glock 45 Gen 5 Crossover comes complete with one adapter plate, three magazines, a magazine loader, cleaning kit, pistol case and gun lock, offering a comprehensive package for shooters seeking versatility, reliability and performance in a handgun.
