Glock 23 Gen 4 .40 S&W

Updated August 24, 2026

This Glock 23 Gen4 semi-automatic pistol is chambered in .40 S&W and represents a later-generation version of one of Glock’s classic compact service pistols. Serial number BKLA186, this example features an approximately 4" barrel with a shiny bore and presents in very good overall condition. The pistol utilizes Glock’s durable polymer frame with the Gen4 textured grip pattern, paired with a steel slide and striker-fired operating system. The Gen4 design introduced several updates over previous generations, including revised grip texture and modular backstrap capability, while retaining the compact proportions that helped make the Glock 23 such a popular duty-size handgun. One magazine is included. The Glock 23 became especially well known during the widespread law-enforcement adoption of the .40 S&W cartridge and remains a recognizable part of Glock’s history. With its Gen4 configuration, very good condition, shiny bore, and substantial .40-caliber chambering, this example offers plenty of appeal for the Glock enthusiast. Please see photos.
