The Magpul PMAG D-50 GL9 is a 50-round drum magazine for 9mm Luger Glock-pattern pistols and PCCs, delivering high capacity in a lightweight, impact-resistant polymer body. A round-count window and ring-pull easy-loading system make topping off painless, and it runs in Glock mag-well carbines and pistols alike. A range-day and competition staple. Black.
