I'm getting a original 79 series colt mk vi Friday and I'm thinking of changing some parts out for wilson combat parts. Should I do this or keep it original for collectors value I plan to shoot it but not carry it its in really good shape . What parts dof you recommend I change out if any and are there any confident gun smith's that don't charge and arm and a leg . I have worked on a lot of guns but never a 1911 is it that difficult I know there's a lot of parts and I'm kind of skiddish about working on it my self . The sights are already changed out. I'm thinking trigger and magwell but not sure . Any help would be great thanks
