This replica pistol is based on the S & W Military and Police firearm. This BB repeater is powered by one 12g CO2 cylinder that hides in the grip of the pistol. An integrated accessory rail underneath the muzzle is great for adding a tactical flashlight or laser. The 19-shot drop-out BB magazine adds an element of realism. Features a manual safety, double-action trigger, and fixed front and rear fiber-optic sights.
