Salient Arms International has built an empire on producing some of the highest quality rifles, sidearms, and firearms parts on the market. Easily identified by their trademarked titanium nitride finished parts that give them a golden luster, SAI has slowly found their way into the airsoft marked as well catering to high-end airsoft enthusiasts who are looking to settle for nothing but the best. They've brought to the table improvements to the very popular Smith & Wesson M&P 9 sidearm. Improvements to the slide in the form of skeletonizing to reduce weight and quicken cycling speed, adding deep and aggressive notches to the slide for non-slip racking of the slide, and high visibility fiber optic front and rear sights all make for a superior performing pistol. A Salient Arms Int'l gun wouldn't be finished without their imitation titanium nitride golden outer barrel either, giving this pistol it's unique look and feel. 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 280-320 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. In addition to it's standard semi-auto firing, a toggle can be switched within the slide to enable fully-automatic firing as well! The switch to turn on full auto is accessed by pulling back the slide and locating it on the underside. The FPS for this pistol is ideal for CQB and training situations. Included with the gun are two interchangeable backstraps, allowing the grip to be customized for the user's comfort and hands of all sizes.
