Lightweight but incredibly strong, the PMAG D-50 GL9 - PCC is a highly-reliable, 9x19mm Parabellum, 50-round drum magazine for many large-format pistols and pistol caliber carbines that feed from GLOCK pattern magazines.* The Magpul D-50 GL9 PCC boasts many of the proven features of its 5.56 and 7.62 predecessors, the PMAG D-60 AR/M4 and PMAG D-50 LR/SR GEN M3 , while providing the user with a similar magazine capacity increase. Providing 50-round capacity, the unique drum configuration keeps the height of the magazine manageable, allowing for prone firing and easier storage. For easy loading, it includes a ratcheting loading lever that removes tension from the internal spring. To keep track of your available firepower, it includes a rounds-remaining rear window, a high-visibility follower and a capacity indication roller. Easily disassembled for cleaning and featuring an innovative bolt hold-open feature, the D-50 GL9 PCC reliably locks the bolt back on empty when used with firearms designed to lock back on GLOCK pattern magazine followers.
