I have a Model 29-4 that has some pitting on the backstrap and quite a bit of holster wear at muzzle and cylinder. I really enjoy the gun and will keep but I've looked into factory refinishing and it seems fairly reasonable. Standard bluing $145.00 plus shipping etc. I think if requested they'll set to factory specs. as well. My question is has anyone done this or any of the other finishes that they offer?
