Sig Sauer Factory MPX 9mm 20 Round Magazine

SIG Sauer Factory MPX 9mm 20 Round Polymer Magazine

Feed your MPX with the Sig Sauer MPX 9mm 20-Round Magazine. This factory magazine is constructed from lightweight, translucent polymer for superior strength and long-lasting field use in virtually any environment. Plus, this magazine features a ribbed surface for positive handling and a sure grip for quick reloads in the field or at the range.

The steel spring and durable polymer follower ensure smooth, reliable feeding in high-stress target and defensive environments. These 20-round magazines provide the perfect balance of firepower and maneuverability, with a smaller profile that’s ideal for target shooting, moving around in vehicles, or just keeping reloads handy.

Patterned after the venerable AR-15 and featuring a revolutionary new gas piston design, Sig Sauer’s MPX is the operator’s choice for 21st Century combat and competition. 

Note: Generation 1 magazines will usually work in Generation 2 guns. But for optimal performance, we strongly recommend purchasing the magazine that matches your gun. Just check an existing mag if you’re not sure.
