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.

We get to see a vintage airsoft pistol reviewed by Mach Sakai. Released in 1988, the MGC S&W M645 Fixed Slide Gun comes with a 15-BB round gs magazine and it has a Cyclone rifled inner barrel for accuracy. This has 0.4J power and since it is rifled, muzzle velocity does not increase. He checks it for external features, operations and performance.
