Made in the USA, The Magpul PMAG 10 GL9, 9x19 - GLOCK 19 was designed for flawless reliability and durability over thousands of rounds. It utilizes the same double stack feed geometry as the standard capacity PMAG GL9 to ensure feeding and to avoid known reliability issues seen in many competitor products on the market. Includes a high visibility controlled-tilt follower, a stainless steel spring, an easily removable floorplate for cleaning, paint pen dot matrix for magazine marking, ridged floorplate edges for better grip, and 10-round indicator windows. The magazine drops free when loaded or unloaded. The PMAG 10 GL9 is compatible with all compact 9mm Glock handguns, as well as sub-compact variants with some protrusion below the grip.
