Magpul PMAG 21 GL9: Competition Capacity Without Compromise
The PMAG 21 GL9 represents a thoughtful solution to the shooter who demands additional capacity without sacrificing reliability or legality. Magpul's proprietary all-polymer construction delivers the durability and flawless function you expect from thousands of rounds downrange.
Key Features
- 21-round capacity meets 140mm competition magazine length requirements
- All-polymer construction provides lightweight durability without corrosion concerns
- Stainless steel spring resists corrosion and maintains consistent feeding pressure
- High-visibility controlled-tilt follower ensures reliable feeding and easy visual confirmation
- Drop-free design functions reliably whether loaded or unloaded
- Easily removable floorplate simplifies cleaning and maintenance
- Capacity indicator windows on both sides show round count at 10, 15, and 21 rounds
- Ridged floorplate edges provide positive grip during magazine changes

Compatibility
The PMAG 21 GL9 works with all full-size, compact, and sub-compact Glock 9mm double-stack variants. Note that the magazine will protrude slightly below the grip on compact and sub-compact models—a minor trade-off for the additional capacity.
Made in the USA
Manufactured to Magpul's exacting standards, the PMAG 21 GL9 delivers the boring reliability you expect from a quality magazine, shift after shift, match after match.
