Sig Sauer MPX 9mm PCB Folding Braced Pistol 6" Barrel - 35 Rd

Trusted by military, law enforcement, and competitive shooters worldwide, the SIG Sauer MPX 9mm Semi-Automatic Pistol sets the standard for modern sub-gun performance, modularity, and battlefield reliability. Engineered with SIG’s ultra-reliable closed-bolt short-stroke gas piston system, the MPX suppresses gas blowback, runs exceptionally clean, and delivers soft-recoiling, flat-shooting control under rapid fire. Built around a 6.0-inch match-grade threaded barrel with an M13.5x1 LH thread pitch, this compact 9mm platform is ideal for rapid-detach suppressor setups and close-quarters maneuvers.

This upgraded MPX configuration comes equipped with the SIG PCB (Pistol Contour Brace) folding brace, allowing the pistol to collapse into an ultra-compact profile for transport while remaining fully operable in the folded position. The lightweight aluminum M-LOK® handguard offers ample rail space for lights, lasers, and foregrips, while also supporting modular handguard swaps for suppressor coverage. Finished in a durable black hardcoat anodization, the SIG MPX ships complete with a high-capacity 35-round magazine for immediate deployment.
