Magpul Industries PMAG D-50 GL9-PCC 50-Round 9mm Drum Magazine (MAG1137)
The Magpul PMAG D-50 GL9-PCC is a 50-round drum magazine for 9x19mm Parabellum pistol caliber carbines built around double-stack 9mm GLOCK-pattern magazine wells. Its shortened feed tower is optimized for PCC use and will not fit GLOCK-pattern handguns.
Features include a ratcheting loading lever to reduce spring tension during loading, stainless-steel internals for corrosion resistance and long-term loaded storage, and a translucent rounds-remaining rear window with a high-visibility follower. The follower design supports bolt lock-back on platforms engineered to lock back on GLOCK-pattern magazine followers.
