MAGPUL PMAG D-50 GL9 FOR GLK 17 50RD

Lightweight but incredibly strong, Magpul's PMAG D-50 GL9 is a highly reliable, 9x19mm Parabellum, 50-round drum magazine optimized for double-stack 9mm Glock handguns. Featuring their innovative bolt hold open, the D-50 reliably locks the bolt back on empty when used with firearms designed to lock back on Glock pattern magazine followers as well as a rounds remaining rear window, a high visibility follower and a capacity indication roller.
