This magazine features a polymer over-molded steel-lined construction that combines durability with lightweight handling. The black finish resists impact and wear, while witness holes on the back provide easy round count visibility. The factory GLOCK polymer baseplate ensures reliable feeding and rugged performance, maintaining the brand’s trusted standards of function and dependability. Compatible with GLOCK 17, 18, 19, 26, and 34 models chambered in 9mm, this 33-round magazine extends well beyond the grip, offering users a substantial ammo reserve for training or tactical applications.
