Glock 20 Gen 4 10mm

Updated August 24, 2026

This Glock 20 Gen4 semi-automatic pistol is chambered in powerful 10mm Auto and represents one of Glock’s most respected full-size large-caliber handgun platforms. Serial number BWTE866, this example features an approximately 4.5" barrel with a shiny bore and presents in very good overall condition. The pistol utilizes Glock’s durable polymer frame with Gen4 grip texture and modular backstrap capability paired with a steel slide and striker-fired operating system. The familiar Glock trigger safety and factory-style sights remain part of the classic configuration. One magazine is included, and the pistol comes housed in a plastic Ruger case rather than a Glock factory case. The Glock 20 has long been one of the benchmark pistols chambered in 10mm Auto, while the Gen4 generation brought updated ergonomics to the proven design. With its powerful chambering, shiny bore, very good condition, and classic Glock profile, this is a strong modern handgun package. Please see photos.
