This is a factory 20-round magazine for 9mm MPX pistols & carbines.

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.

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.

Factory magazines are built to Sig Sauer’s strict specifications, featuring reinforced feed lips and durable translucent polymer construction. Multiple capacities available.

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 (Black follower = Gen 1, Green follower = Gen 2).
