The officially licensed M&P 9 Full Size gas blowback pistol is made to exact specifications to replicate the real gun as closely as possible. This airsoft M&P 9 is made by VFC, a company well known for making top of the line airsoft products. It features official S&W trademarks fully engraved on the slide, pistol grip, and magazine. Everything about the gun is almost completely identical to the real S&W M&P except for the fact that the airsoft version shoots 6mm plastic BBs. This gun will fit perfectly in any holster designed for the M&P 9 or M&P 40. The gun shoots at approximately 280-300 FPS with 0.20g BBs. It is very gas efficient; in our tests we were able to fire two full 23 round magazines on one gas fill on semi automatic. The pistol has full blowback to replicate the action of the real firearm. This means that the slide shoots back with each shot and will lock back after the last BB has been fired. A cool feature on this pistol is that it has a full auto function. The switch to turn on full auto is accessed by pulling back the slide. The FPS is ideal for CQB and training situations. Included with the gun are two changeable backstraps, allowing the grip to be customized for the user's comfort.
