I had a few oldies that were left to me by my Dad. I buggered up the finish on an old Smith (pre-Mod 10) M&P. I consider the money I spent to have Smith re-finish the piece some of the best cash I have ever spent. It now sits in a hermetically sealed shadow box, with a picture of my Dad holding it.
I guess my point is, have it re-finished by Smith, even if you have to save up to do it. You will then have a perfect piece to pass on to the next generation.
Just my opinion
