The ProMag Sig MPX 9mm Luger drum magazine is a high-capacity option for shooters running the Sig Sauer MPX platform. With a 50-round capacity, this polymer drum magazine lets you extend trigger time and reduce mag changes on the range or in training scenarios. Built stateside and engineered for reliable feeding, it's a practical upgrade for anyone looking to maximize round count per reload.
ProMag backs this drum with a lifetime guarantee against manufacturer defects—a real commitment to standing behind their gear. The magazine uses precision heat-treated chrome silicon wire springs throughout, the kind of materials and process detail that separates dependable magazines from the cheap stuff. Every unit goes through multiple checks during assembly to keep quality consistent, so you're not gambling on whether this mag will run when you need it.
The rugged polymer construction keeps weight down while the easy-loading design means you're not fighting with a stiff feed system when you're topping it up. If you shoot the MPX and want to push round counts without constant reloads, this 50-rounder deserves a spot in your gear bag.
