The Gen5 configuration brings practical updates to the G20 platform. Ambidextrous slide stop levers aid manipulation from either side, and the flared magwell speeds reloads while maintaining a secure, full-size grip. Front and rear slide serrations provide confident purchase for press checks and slide control.
The 4.61 in Glock Marksman Barrel features enhanced rifling and an improved crown for consistent accuracy and durability. Its steel construction and polygonal profile complement the 10mm chambering for reliable performance.
The slide wears Glock's nDLC finish for corrosion and wear resistance, and it includes a MOS optics cut for mounting patterns that are compatible with Glock's Modular Optic System. Fixed Glock polymer sights come installed, with a white dot front and white U-notch rear for a familiar sight picture.
The pistol retains Glock's Safe Action system and a standard 15+1 capacity using factory 10mm magazines. An accessory rail on the frame accepts compatible weapon lights or other rail-mounted accessories as desired.
U.S. origin is confirmed by the "GLOCK US" marking on the barrel hood and the "MADE IN USA GLOCK, INC., SMYRNA, GA, USA" molding on the right side of the frame/grip. The slide itself is marked "20 Gen5 USA 10mm Auto" and bears a P-in-pentagon proof. The included magazines feature orange followers and bases marked 1622-02, aligning with current 10mm factory production.
