Glock 21 13-Round Magazine

Glock 21 Factory Magazine

This is the genuine Glock 13-round magazine for the full-size Glock 21 in .45 ACP, the .45 Automatic Colt Pistol cartridge. It is the standard-capacity magazine Glock ships with the pistol, so it suits owners who want spares for the range, a carry reload, or a replacement for a worn original. It also fits the compact Glock 30 and the long-slide Glock 41, which makes it a useful shared magazine if you own more than one .45 Glock.

Features

• 13-Round Capacity — Holds 13 rounds of .45 ACP, the factory standard load for the Glock 21.
• Genuine Glock Manufacture — Made by Glock rather than a third-party copy, so the dimensions and spring match what the pistol was designed around.
• Polymer Body With Steel Insert — A hardened steel liner sits inside the polymer shell to help the magazine hold its shape under a full spring load.
• Double-Cut Design — Magazine catch notches on both sides let it lock in whether the pistol's release is set up for right- or left-handed use, as on reversible Gen 4 frames.
• Metal Spring — A metal follower spring pushes each round up to the feed lips for the next cycle.
• Flat Base Plate — The plain floor plate sits flush with the bottom of a Glock 21 grip and adds no extra length.
• Multi-Model Fit — Works in the Glock 21, 21SF, 30, 30SF and 41.
• Black Finish — Matte black polymer that matches the factory frame.

Fit And Construction

The magazine is compatible with Gen 2, Gen 3 and Gen 4 Glock 21 pistols, plus the SF (short frame) variants, the Glock 30 family and the Glock 41. In the compact Glock 30 and 30SF it extends below the grip, since it is sized for the full-size frame. Construction is Glock's usual pattern: a black polymer body molded over a hardened steel insert, a metal spring and a flat base plate.
