The G20 Gen4 pairs 10mm Auto performance with a 15+1 capacity using Glock-marked, polymer/steel-lined double‑stack magazines with witness holes. Its 4.6 in steel barrel features Glock polygonal rifling, and the nitrided finish provides a durable exterior. Fixed polymer sights include a white dot front and white U-notch rear for a standard Glock sight picture.
Gen4 enhancements include the dual captive recoil spring assembly, an enlarged reversible magazine release, and modular backstrap compatibility. The Gen4 rough textured frame with finger grooves provides added purchase, and the standard Glock accessory rail with one slot on the dustcover supports common weapon-mounted lights. Rear slide serrations aid manipulation; the slide is non-ported and non-cut.
This pistol retains key Glock functional features: a striker-fired Safe Action system and an extractor that also serves as a loaded-chamber indicator. Factory markings include "MADE IN AUSTRIA GLOCK, INC., SMYRNA, GA." The slide, barrel, and frame share matching serials.
Overall, this is a correct, Austrian-made Gen4 configuration with the features buyers expect in a full-size 10mm: strong capacity, Gen4 ergonomics, and the included factory case and magazines.
