The SIG MPX platform’s short-stroke piston system is engineered to run cleaner than direct blowback designs, reducing fouling and heat transfer to the shooter. Chambered in 9mm, it utilizes common, low-recoil ammunition. The integrally shrouded barrel minimizes overall length while containing muzzle blast. This configuration is suited for dynamic shooting sports, home defense, and as a highly compact personal defense weapon where size and reliability are critical.
