So I want a 1911. More just because I want one than anything else. I want something that's accurate, reliable, and has a good fit and finish, doesn't have to be super tight. I know there's a lot of other brands out there (kimber) but I've narrowed it down to colt or sig as the one I want. Either a colt government model, or a full size GSR revolution. From what I've heard the only difference between the 70 and 80 series is a firing pin block, is that true? Let me know what you think of these two guns.
