I dunno how long that finish will hold up. Some of that may depend on the finish underneath. I've seen a couple of friends guns that had that done and they look OK.Hmm, is there any sort of bushing that stabilizes the muzzle? If there is, have a look at any wear patterns it's producing. It's be a shame to spend the time and money to get it done if it's only going to be ruined in short order.
