The Magpul GLOCK magazines come with many of their other platform PMAG features, including 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 GL 9 drops free from the firearm whether it’s loaded or unloaded. All with the same boring reliability you expect from an OEM magazine. 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.
