This BB gun is a replica pistol based on the S&W Military and Police firearm. The M&P air pistol is a BB repeater powered by one 12g CO2 cylinder that hides in the grip of the BB pistol. An integrated accessory rail underneath the muzzle is a great place to add a tactical flashlight or an air gun laser. An element of realism is added with a 19-shot drop out BB magazine. The Smith & Wesson M&P CO2 pistol has a manual safety, double action trigger that’s amazingly close to the actual handgun, and fixed front and rear fiber optic sights.

The shape- weight and function of the Smith & Wesson M&P 40 by Umarex has all the similarity of the live-fire handgun. This BB replica is not only a great BB gun for some fun plinking, but also makes a great target shooting and training pistol for S&W M&P firearm owners.
