Magpul PMAG 21 GL9 9mm 21-Round Magazine for Glock – MAG661-BLK
Made in the USA, the PMAG 21 GL9 is a 21-round 9mm magazine built for Glock double-stack pistols, engineered with Magpul's proprietary all-polymer construction for maximum reliability and durability. Meeting the 140MM competition magazine length, it offers additional capacity without the need for expensive base extensions. The magazine features a high-visibility, controlled-tilt follower, corrosion-resistant stainless steel spring, and a floorplate that's easily removed for cleaning. Additional features include paint pen dot matrix panels for magazine marking, ridged floorplate edges for improved grip, and dual capacity indicator windows for quick round count checks. The PMAG 21 GL9 drops free whether loaded or unloaded and works with all full-size, compact, and sub-compact double-stack Glock 9mm handgun variants (with some grip protrusion on compact/sub-compact models).
