Ed Brown GLMAG31 9mm Luger 31-Rd Magazine for Glock 17/18/19/26/34

The Ed Brown GLMAG31 is an extended-capacity, 31-round replacement magazine built for 9mm Luger Glock-pattern pistols. Drop-in fit for the Glock 17, 18, 19, 26, and 34, the GLMAG31 is also widely used in 9mm pistol-caliber carbines that accept Glock-pattern magazines, giving you substantially more firepower than standard 15- or 17-round factory Glock mags.

Inside, the magazine pairs a steel liner for smooth, reliable feeding and durability with a polymer outer body that resists corrosion, reduces weight, and gives the mag a clean black finish that blends with factory Glock pistols. Finished to Ed Brown's premium standards, the GLMAG31 is a popular choice for range training, competition, and defensive setups that demand extra capacity.
