I have a 1964 Colt SAA that is factory nickeled that I use as a shooter. Last range out I noticed upon cleaning that the plating is starting to flake on one chamber at the front. Since this is my shooter I was thinking about replating the whole revolver in either hard chrome or electroless nickel. I have seen factory SAAs hard chromed that look great but very limited and was wondering who plated them for Colt. Anyone know who did the work? I was guessing perhaps Metalife. If I decide not to replate the entire revolver I may just have the cylinder renickeled, any suggestions on who to have do it?
