ProMag has grown to become one of the largest US-based magazine manufacturers since they got their start in 1978. This 15 round for Glock v magazine is made right here in the U.S.A. by American workers. The magazine is constructed of ProMag's proprietary Dupont Zytel derived high impact polymer to give a long service life in the toughest conditions, with a steel insert that prevents feed lip distortion for added durability to the feed lips. For added reliability, ProMag also included a chrome silicon spring that resists taking a set no matter how long you leave the magazine loaded.
