The SW M&P is a polymer-framed, short recoil operated, locked breech semi-automatic pistol introduced in the summer of 2005. It uses a Browning-type locking system. While targeted at law enforcement agencies, the MP is also widely available on the commercial market.

The M&P is a hybrid evolution of the SW99 design but does not share parts compatibility with the Sigma. The M&P design has an improved trigger and enhanced ergonomics that allow for end-user customization. An industry standard picatinny rail and a higher grip has been afforded with an improved grip and beavertail. Many of the ergonomic study elements that had been incorporated into the Sigma and the SW99 were brought over to the MP. The improved trigger weight and feel and the unique takedown method (not requiring a dry-fire pull of the trigger) were meant to set the MP apart from the popular model G pistols.

KWC are known for making quality full metal handguns in the airsoft market and have a good reputation for their build quality. This particular M&P40 features under rail, safety and extra grips for different size hands whilst still keeping within CQB power limits of 400 FPS.
