The MAGPUL PMAG 17 GL9 is a 17-round Glock 9mm handgun magazine that uses High visibility controlled-tilt follower, stainless steel spring, easily removable floorplate for cleaning, paint pen dot matrix for mag marking, ridged floorplate edges for better grip, and 17rd indicator windows. The MAGPUL PMAG 17 GL9 drops free loaded or unloaded. The new proprietary all-polymer construction has proven to be extremely reliable and durable over thousands of rounds.
