GLOCK 23 .40 S&W Factory Magazine - 10 Round - Handgun Magazines

GLOCK's factory .40 S&W magazine for the GLOCK G23 combines a hardened steel internal structure with high-impact polymer construction — the same magazine that ships with new GLOCK pistols, built to the same specifications, providing the feeding reliability and durability that the platform is known for in a 10-round capacity.

This is a genuine GLOCK factory original .40 S&W magazine with 10-round capacity for the GLOCK G23. It combines a hardened steel core with high-tech polymer construction and a black finish. As a factory-original component, it is built to the same dimensional and material specifications as the magazines shipped with new GLOCK pistols.

GLOCK's magazine construction philosophy prioritizes feeding reliability through the service life of the magazine rather than cost minimization. The hardened steel internal components — the follower spring and the locking block that engages the pistol's magazine catch — are dimensionally consistent and resistant to the fatigue and deformation that cause aftermarket magazine springs to weaken and followers to tilt over time, both of which are primary causes of feeding failures in semi-automatic pistols. The high-impact polymer body provides the structural integrity to resist the compression and impact loads of being dropped, stomped, and loaded to full capacity repeatedly, while remaining lighter than an all-steel magazine. As a factory GLOCK component, the dimensional tolerances of the magazine body, the feed lips, and the follower geometry are matched to the tolerances of GLOCK's chamber and feed ramp specifications — the dimensional relationship that determines whether a magazine will feed reliably or intermittently cause presentation failures into the chamber. Aftermarket magazines built to looser tolerances may function adequately in benign conditions but exhibit marginal feeding under recoil or with certain bullet profiles. The factory GLOCK magazine eliminates that variable.

Caliber: .40 S&W. Capacity: 10 rounds. Compatible: GLOCK G23. Construction: hardened steel core, high-impact polymer body. Finish: black. Factory GLOCK original.

Factory GLOCK construction means dimensional tolerances matched to GLOCK chamber and feed ramp specifications — eliminating the marginal feeding risk of aftermarket magazines with looser tolerances. Hardened steel internal components resist the fatigue and deformation that weaken aftermarket springs and followers over time. Same magazine specification as new pistol shipments.

The right magazine for GLOCK G23 owners who want factory-specification feeding reliability — genuine GLOCK construction, matched tolerances, and the same component quality as the magazine that shipped with the pistol.
