The G20 Gen4 configuration delivers Gen4 ergonomics and control in 10mm Auto. The Gen4 Rough Textured Frame with finger grooves provides a secure hold, while the Modular Backstrap System lets the shooter tailor grip size, including beavertail options. The enlarged, reversible magazine catch supports right- or left-handed magazine changes.
The slide wears a matte duty finish with rear-only serrations and houses a dual recoil spring assembly designed for durability and recoil management. The 4.6 inch steel barrel uses Glock's polygonal rifling, and the pistol retains Glock's Safe Action system with three passive mechanical safeties.
Sighting is straightforward with fixed Glock-pattern sights: a white-dot front and white-outline rear. The sight radius is 6.77 inches. A Glock Universal (1-slot) accessory rail on the dust cover accepts compatible lights or accessories.
This pistol is marked with Austria origin, including "MADE IN AUSTRIA" and Glock, Inc. Smyrna, GA markings on the slide and an "AT" mark on the barrel hood. It has matching serials on the slide, barrel (serial on lug), and frame, and includes the molded U.S. Pat. 5,166,677 on the grip.
The slide is configured with rear serrations and no optics cut.
