The Sig Sauer MPX 9mm Luger polymer magazine is a factory-original mag engineered specifically for the MPX platform. Whether you're running the MPX at the range, in competition, or as a duty gun, this magazine delivers the reliability Sig built its reputation on. It's the result of a rigorous 2-year design cycle focused on meeting Sig's exacting quality standards while maximizing performance in the MPX system.
What sets this mag apart is its hybrid construction: metal feed-lips that withstand thousands of rounds and rough handling, paired with a lightweight polymer body that resists warping and maintains shape under pressure. That combination matters when you're counting on your gear to perform. The black polymer finish is durable and low-profile, and it works with all generations of the Sig MPX platform.
Available in your choice of capacity, this magazine is built to be a workhorse—whether you're stocking spares for a training day or gearing up for serious shooting. It's the kind of no-nonsense component that disappears into the background because it simply works.
