SIG Sauer MPX K 9mm Pistol w/ PCB Folding Brace – PMPX-4B-9-35

The SIG Sauer MPX K 9mm Pistol (WPMPX-4B-9-35) is a compact, high-performance pistol caliber platform engineered for superior reliability, fast handling, and exceptional accuracy. Designed around SIG Sauer's proven short-stroke gas piston operating system, the MPX K delivers smooth cycling and reduced recoil compared to traditional blowback-operated PCCs, making it a favorite among law enforcement professionals, tactical teams, competitive shooters, and discerning firearm enthusiasts.

Featuring a 4.5-inch barrel, the MPX K offers outstanding maneuverability in confined spaces while maintaining excellent ballistic performance. The included SIG PCB folding brace provides added stability without sacrificing the platform's compact footprint, making it ideal for home defense, vehicle deployment, range use, and tactical applications.

The free-floating M-LOK handguard allows users to customize the platform with lights, lasers, grips, and other mission-essential accessories. A full-length Picatinny top rail provides ample space for optics, backup sights, and magnifiers, while the flat-blade trigger delivers a crisp, consistent trigger pull for enhanced accuracy.

Chambered in 9mm Luger and supplied with a 35-round magazine, the MPX K combines the familiar ergonomics of the AR platform with the controllability and economy of the 9mm cartridge. Whether used for duty, training, home defense, or recreational shooting, the MPX K is one of the most versatile pistol caliber firearms available today.

At Accurate Tactical, we proudly offer premium firearms trusted by law enforcement agencies, military personnel, and responsible firearm owners nationwide.
