Magpul PMAG D-50 MP 9mm 50-Round Drum Magazine for HK MP5/SP5 - Black Polymer

The Magpul PMAG D-50 MP 9mm 50-round drum magazine brings serious capacity to HK MP5 and SP5 platforms—and MP5-pattern clones—where high-capacity options have been scarce. Until Magpul developed this design, shooters running the iconic MP5 had to make do with standard box mags. This drum changes that, letting you stay in the fight with 50 rounds of 9mm without a reload.

Built from Magpul's proven impact-resistant polymer, the PMAG D-50 MP incorporates a ratcheting loading lever that makes filling the drum faster and easier than fighting a stiff spring. A rear witness window and round-count indicator help you track your round count at a glance—critical when you're running high-volume drills or extended range sessions. The drum disassembles for cleaning and maintenance, and includes a paint-pen dot matrix so you can mark your preferred load level or add notes.

One smart design touch: Magpul engineered the overall height to stay manageable so you can still shoot prone without the magazine getting in the way. That balance between capacity and shootability makes it genuinely practical, not just a novelty. Whether you're running a registered HK94, an SP5, or a quality MP5-pattern clone, this magazine feeds reliably and feels solid in hand.
