Key features and ergonomics
The GLOCK G21 GEN 5 brings multiple refinements: a flared mag-well with a larger funnel speeds reloads, and Glock Marksman Barrel (GMB) polygonal rifling with a target-style crown improves group consistency and muzzle protection. The Gen5 removes finger grooves and adds ambidextrous slide stop levers for improved handling by left- and right-handed shooters. Multiple backstraps and an enlarged floor plate give customization for hand circumference and easier magazine extraction.
Caliber performance and handling
The .45 AUTO remains a respected service and defensive caliber for its terminal performance. In the G21 Gen 5, the 4.61″ barrel balances velocity and compact carry length while the Gen5 platform’s tuning yields light, manageable recoil for faster follow-up shots. Fixed sights provide a durable sight picture out of the box and the optics-ready slide accepts red-dot plates for modern sighting solutions.
Reliability and safety systems
Like other Glock pistols, the Safe Action System uses three passive, automatic safeties that disengage sequentially with the trigger pull and re-engage when released. The tighter chamber specs on the GMB and robust Gen5 internals maintain Glock’s reputation for reliability in adverse conditions.
Package contents are pragmatic: this Semi Auto arrives with three magazines, a mag loader, cleaning kit, pistol case, and gun lock — a complete starter set for owners. At a listed price of $668.99, it provides Gen5 features and optics readiness at competitive value. View product details and pricing
