UPDATE: Clarification from Echigoya about the muzzle velocity in the comments area of this page. Now available at Echigoya for US$158.00, the Tokyo Marui Colt Government 1911 Mark IV gas blowback pistol has an ABS frame and slide, magazine capacity of 28+1, and we couldn't just believe our eyes when reading the packaging as it indicates that its muzzle velocity is 825fps. I don't know if this is correct since we haven't read any corrobarating document, even at Tokyo Marui's website.

It's still safe to assume that it's within the legal limits of Japan. Click on the image below to go to the product page.
