Designed for your Glock® 21 pistol in .45 ACP, this 40-round drum magazine's housing is constructed of proprietary DuPont® Zytel™ based polymer, making it a lightweight, high-capacity option for your Glock pistol. Additionally, this drum features an injection-molded magazine follower, meaning you get a stronger, more reliable, and efficient follower and fewer failures. And with the over-molded stamped steel feed lips and magazine catch, you get durability. Also, including a heat-treated, stainless-steel spring, this drum is corrosion-resistant—making it great for shooting in various climates—and holds up to the shock of impact loads.
