Agree with this. The pistol has survived this long and looks that good leave it be. Get a newer mil spec and hot rod it. In my opinion it should be shot occasionally (that’s what they are for) but otherwise baby it. Same as an unmolested driver quality classic car.You can go get a new 70 series colt off the shelf to build..? What would be the benefit in chopping that one up ? You can't build that kinda awesome .. If i wanted a hot rodded gun (and i do..lol).. i would sell that one to somebody who appreciates it for what it is, and get a different one to build. You all i'm sure know more about this stuff than i do.. Maybe that one "built" would be worth more than a garden variety gun..? But my reflex response would be to preserve that one.
