Magpul PMAG GL9 21 Rd. Glock Magazine - 9mm

The Magpul PMAG 21 GL9 provides 21-round capacity for compatible double-stack Glock 9mm pistols without an added magazine extension. Its polymer body meets the overall length requirements for a 140 mm competition magazine and is designed to drop free whether loaded or unloaded.

A high-visibility, controlled-tilt follower and stainless steel spring support reliable feeding. Capacity windows help track remaining rounds, while the removable floorplate simplifies cleaning. Ridged floorplate edges provide added grip, and a paint-pen dot matrix lets you identify individual magazines.
