Mach Sakai reviews the Tanaka Works Japan Maritime Self-Defense Force SIG SAUER P220 Heavyweight Pistol. This is a good piece like the real steel version with blowback, functioning decocking lever, triggerr, magazine release, metal made hammer, stop, magazine release and more features. It has a thin pistol grip making it easier to hold and he finds operating it to be quite good. He also says it is a good side arm for airsoft games.
