The Gen4 configuration brings the dual recoil spring assembly and modular backstrap interface to the G20 platform, pairing a 4.61 in cold hammer forged steel barrel with a full-size frame to handle the 10mm Auto cartridge. Standard capacity is 15+1, with two factory 15-round magazines included.
Ergonomics and controls reflect the Gen4 updates: an RTF textured grip with finger grooves, an enlarged reversible magazine release, and Glock's trigger safety with a safety tab. The polymer frame incorporates the Glock Universal single-slot accessory rail for mounting compatible lights.
The slide uses rear-only vertical serrations for a consistent grasp. Sights are the factory fixed polymer set with a white dot front and a white-outlined rear notch, paired with a 6.77 in sight radius. The barrel features polygonal rifling with a 1:9.84 in twist.
Markings include the AT mark on the barrel hood, visible proof marks, and "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA." Matching serial numbers on the frame, slide, and barrel provide added documentation value for buyers who want a cohesive factory set.
