Magpul PMAG 21 GL9 magazine for Glock 9x19 21 rounds - Black

The Magpul PMAG 21 GL9 is a 21-round, 9x19 mm Parabellum polymer magazine for double-stack Glock 9mm pistols, featuring increased capacity compared to the standard magazine.

The high-visibility, controlled-tilt follower allows for immediate visual confirmation and smooth feeding, and locks the slide open when the magazine is empty.
