I had 6.5" 29-2 nickel for a long time. I traded it off some years ago. I carried it quite a bit for a few years. The finish is very durable. It did show scuffs as time went on, but it never flaked.
It was an excellent gun. I don't regret its passing, but I do remember our time together fondly.
FYI- The Mother's will take light scuffs out. It worked bery well on 2 blemishes on the left side of this gun.
