Magpul PMAG 21 GL9 - GLOCK, Black

The PMAG 21 GL9 is a 21-round GLOCK 9mm handgun magazine featuring our proprietary all-polymer construction for flawless reliability and durability over thousands of rounds. Meeting the overall length requirements for a 140MM competition magazine, the PMAG 21 GL9 offers additional capacity without the need for expensive extensions.

Our GLOCK magazines come with many of our other platform PMAG features, including a high visibility controlled-tilt follower, a stainless steel spring, a floorplate that's easily removable for cleaning, a paint pen dot matrix for magazine marking, ridged floorplate edges for better grip, and capacity indicator windows. The PMAG 21 GL 9 drops free from the firearm whether it's loaded or unloaded. All with the same boring reliability you expect from an OEM magazine.

The PMAG 21 GL9 is compatible with all full-size, compact, and sub-compact double-stack GLOCK 9mm variants with some protrusion below the grip.

Made in the USA.
