Providing a high-value alternative to expensive factory Glock magazines, Korean-made Glock-compatible magazines are perfect for rough use, tactical drills, and any other application that might put aggressive wear on magazines and equipment. These 9mm Glock-compatible magazines are built with the same polymer and steel design as factory Glock magazines. The magazines are compatible with all-generation Glock handguns and Glock-compatible firearms. The internal springs are made from heat-treated chrome silicon wire, and like many new extended magazines might need to be loaded and reloaded several times before accepting total capacity.
