ProMag has grown to become one of the largest US-based magazine manufacturers since they got their start in 1978. This 10 round GLOCK 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.
