Glock Factory Magazine Gen 5 for Glock 23 .40 S&W - 13-Round Polymer Black

A Glock Factory Magazine Gen 5 for Glock 23 .40 S&W is a genuine OEM magazine engineered by Glock for the Glock 23 Gen 5 platform. Built to the same tolerances and standards as the pistol itself, this 13-round polymer magazine delivers the dependable, no-nonsense reliability you expect from factory Glock hardware—whether you're running a duty carry setup, competition load-outs, or putting rounds downrange at the range.

Like all Gen 5 mags, this one features Glock's updated floor plate design (01 cut) for improved grip during speed reloads and faster magazine changes under pressure. The reinforced polymer body with internal steel liner stands up to years of heavy use and hard drops without losing function. An orange follower gives you instant visual feedback on round count at a glance, and numbered witness holes along the side let you confirm how many rounds are seated without removing the mag from your rig.

Drop-free performance is standard—the magazine ejects cleanly and smoothly from the Glock 23 Gen 5 when the catch is pressed, so reload drills stay fast and consistent. This is a straightforward, no-frills component built to Glock's exacting factory standards. If you run a Glock 23 Gen 5 in .40 S&W, having spares on hand is smart practice.
