Glock G21/41 Pistol Magazine .45 ACP 13 Rounds Polymer/Steel, Black

The Glock G21/41 .45 ACP 13-Round Magazine is a factory-original component designed to deliver maximum reliability, durability, and performance in Glock’s big-bore platforms. Constructed with a crack-resistant black polymer body over full-length steel inserts, it provides the rigidity of metal with the impact resistance and corrosion protection of polymer. Precision-engineered for flawless feeding, the magazine incorporates a high-tensile steel spring and a black polymer follower to maintain consistent pressure and smooth cycling under extreme conditions. Its double-cut magazine body accommodates both standard and reversible magazine release setups on Gen4 models, ensuring universal compatibility across all Glock 21 and 41 variants, as well as certain compact and subcompact .45 ACP Glock models. Numbered witness holes along the spine allow for quick capacity checks, while the flat polymer baseplate keeps the profile compact for duty, range, or personal defense applications. Engineered to drop free when released, it enables rapid reloads without snagging, supporting high-performance shooting in both competitive and tactical environments.
