Sig Sauer’s X-Five CO2 Pellet Pistol is based on the high-end target pistol made by the expert gunsmiths at Sig Sauer’s Master Shop in Germany. It features the same look, feel, weight, and operation. Appearance wise, the X-FIVE Pellet Pistol features the exact same profile. The X-FIVE Pellet Pistol also mimics the same weight and operation for an extra level of realism. Just like the center-fire version, the X-FIVE Pellet Pistol utilizes a double-action/single-action semiautomatic blow-back operation, and the safety and magazine release are in the same locations. A picatinny rail allows a light or laser to be installed, and a threaded barrel allows a muzzle device to be installed. Other features of the X-FIVE Pellet Pistol include a patented cam-lever system for quickly replacing CO2 cylinders, and high-visibility sights ensure superior accuracy.
