Magpul PMAG 21 GL9 – GLOCK

The PMAG 21 GL9 is a 21-round GLOCK 9mm handgun magazine, crafted with all-polymer construction for exceptional reliability and durability over thousands of rounds. Meeting 140MM competition magazine length requirements, it provides extra capacity without costly extensions.

Featuring high visibility controlled-tilt follower, stainless steel spring, easily removable floorplate for cleaning, paint pen dot matrix for marking, ridged floorplate edges, and capacity indicator windows, the PMAG 21 GL9 consistently drops free, whether loaded or unloaded.

Compatible with all full-size, compact, and sub-compact double-stack GLOCK 9mm variants, with slight protrusion below the grip.

Proudly made in the USA.
