Sig Sauer MPX Gen 2 9mm Luger Polymer Translucent Magazine

The Sig Sauer MPX Gen 2 9mm Luger polymer translucent magazine is a factory mag built to feed reliably in the Sig MPX platform. If you run an MPX carbine or pistol in 9mm, you need magazines you can trust—and Sig's own magazines are engineered to the same exacting tolerances as the gun itself. The translucent polymer body lets you see your round count at a glance, and the durable construction holds up to daily use at the range or in the field.

With a 10-round capacity, this magazine delivers practical volume without excessive length or weight. The polymer construction keeps things light while maintaining the rigidity needed for consistent feeding. Whether you're building a backyard plinker, a duty setup, or a compact 9mm for home defense, having multiple mags on hand means more trigger time and less downtime.

Sig magazines are made to Sig specs—period. No guesswork, no compromise. If you're serious about your MPX platform, start with factory mags and add spares as your collection grows.
