The 4.61 in Glock Marksman Barrel features enhanced polygonal rifling and a revised crown, supporting the G20’s 10mm performance while providing a smooth, clean bore. The full-size frame offers a 15+1 capacity in 10mm, and the Gen5 flared magwell aids fast, consistent reloads.
The Gen5 MOS slide is finished in durable nDLC and includes both front and rear serrations. Factory fixed sights provide a clear, straightforward sight picture.
Controls are Gen5-correct with ambidextrous slide stop levers and a reversible magazine release. The accessory rail uses a single slot for lights or other compatible attachments, and the polymer frame maintains Glock's familiar ergonomics.
Origin and markings are clearly defined: the slide is roll-marked "20 Gen5 USA 10mm Auto" with the Glock logo. The frame bears the "MADE IN USA – GLOCK, INC., SMYRNA, GA" origin marking. Barrel, slide, and frame carry matching serial numbers, adding cohesion to this U.S.-produced G20 Gen5 MOS.
