Made in the USA, the Magpul PMAG 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. It
features 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 GL9 drops free from the firearm whether it’s
loaded or unloaded. 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.
