Product DescriptionThe Magpul PMAG D-50 is a lightweight yet incredibly strong 50-round drum magazine for 9x19mm Parabellum (9mm Luger) pistol caliber carbines and other platforms that feed from double-stack Glock-pattern magazines. Built with next-generation impact and crush-resistant polymer and robust stainless-steel internals, it's engineered for reliable feeding and durability, including corrosion resistance and long-term loaded storage.
