Lightweight but incredibly strong, this PMAG D-50 EV9 is a highly-reliable, 9x19mm Parabellum, 50-round drum magazine for large-format pistols and pistol caliber carbines that feed from CZ Scorpion EVO 3-pattern magazines. The D-50 EV9 boasts many of the proven features of its 5.56 and 7.62 predecessors, the PMAG D-60 AR/M4 GEN M3 and PMAG D-50 LR/SR GEN M3 , while providing the user with a similar magazine capacity increase. The D-50 EV9 features a ratcheting loading lever that removes tension from the internal spring. To keep track of your available firepower, this magazine also includes a rounds-remaining rear window and a high-visibility follower tip. Easily disassembled for cleaning and featuring an innovative bolt hold-open feature, the D-50 EV9 reliably locks the bolt back on empty when used with firearms designed to lock back on CZ Scorpion EVO 3-pattern magazine followers.
