The slide features an nDLC finish for durability, plus front and rear serrations for confident manipulation. Fixed polymer sights include a white-dot front and white-outline U-notch rear.
Ergonomics reflect the Gen5 pattern: no finger grooves, a mildly flared magwell for smoother reloads, and a rough-textured frame for consistent control. Controls include ambidextrous slide stop levers and a reversible magazine release to accommodate a wide range of shooters.
Chambered in .45 ACP, this full-size G21 carries a 13+1 capacity. The short-recoil, striker-fired Safe Action system provides a consistent factory-standard trigger pull. The barrel uses Glock polygonal rifling.
