I have a kwc colt government model 1911. Co2 and internally the same as the EF 1911 tac. Just installed a new barrel and hop up with a threaded barrel. Shoots great and mag has no leaks. Only flaw is cosmetic, the back loop of the hammer broke off, but that doesn’t effect performance. Comes with a safari land drop-leg holster and a functional surefire x300 light. Price is negotiable, message for more pics/vids or info. PayPal ONLY
