hi guys! i bought the slide and barrel from one of our good friends here, an armscor commander slide (in white, no markings of anything) and a commander bull barrel. i bought it for my issued colt mk4 series 80, use its receiver to make a 2-in-1 gun. since i always carry my service fa in plain clothes, it might be a better carry than the standard 5" barrel. yet i'm having second thought of making it to another gun, with an armscor hi-cap frame. well any suggestions and donations as well of your used/old parts?
