Mach Sakai recently had a great time at the range with the Tokyo Marui S&W M645 airsoft pistol, a model based on S&W's first .45 caliber automatic pistol that was introduced in 1985. This air-cocking model is simple to operate: users manually prepare each shot by pulling back the slide, after which a pull of the trigger fires the BB bullet. Enhancing its performance, the pistol features a hop-up system which imparts rotation to the BBs, allowing them to fly further with less power. For safety, a lever on the left side of the main body engages the safety, preventing accidental firing by locking the trigger
