Made in the USA, the PMAG 15 GL9 is a Glock 9mm handgun magazine featuring our proprietary all-polymer construction for flawless reliability and durability over thousands of rounds. It includes a high visibility controlled-tilt follower, a stainless steel spring, an easily removable floorplate for cleaning, paint pen dot matrix for mag marking, ridged floorplate edges for better grip, and 15-round indicator windows. The magazine drops free when loaded or unloaded. The PMAG 15 GL9 is compatible with Glock G19 handguns as well as sub-compact variants with some protrusion below the grip.
