The PMAG 21 GL9 is a 21-round Glock 9mm handgun magazine featuring 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.

The PMAG Glock magazines come with many of the 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.
