Overview

The Magpul PMAG 21 GL9 is a 21-round 9mm magazine designed for Glock handguns, featuring a proprietary all-polymer construction built for durability and reliability. Meeting the length requirements for 140mm competition magazines, it provides extended capacity without the need for expensive baseplate extensions. Features include a high-visibility controlled-tilt follower, a stainless steel spring, a removable floorplate with ridged edges, a paint pen dot matrix for marking, and full magazine capacity indicator windows. The magazine drops free whether loaded or empty and is compatible with full-size, compact, and sub-compact double-stack 9mm Glock variants.
