The SIG SAUER MPX K is the compact powerhouse of SIG's MPX line, a 9mm large-format pistol built around a short-stroke gas piston system that runs cleaner and softer than blowback designs. This configuration pairs a 4.5" barrel with M-LOK handguard, ambidextrous controls, and a rear picatinny interface for brace or accessory mounting. The MPX platform has earned a strong following among competitive PCC shooters and home-defense users alike for its light recoil impulse, AR-style ergonomics, and consistent reliability with a wide range of 9mm ammunition. Ships with a 35-round magazine where legal.
