The Magpul GL Enhanced Magazine Well for Glock 19 Gen 3 is a high performance Glock frame magazine well designed to enhance and ensure positive magazine insertion in high stress situations. Its sleek and ergonomic design features also provide excellent concealment and ensure minimal printing to the user's clothing. Ramp and edge geometry allow for the smooth removal of stuck magazines during reloads. Optimized for use with standard capacity Glock factory magazines, Magpul GL magazines, and a variety of aftermarket floorplates and extensions that are available for both. Recent generations of reduced capacity (10 rd) factory Glock magazines have several dimensional differences which may interfere with any magazine well, including the Magpul GL Enhanced Magazine Well. Some large aftermarket floorplates may also interfere. Made in the USA.
