There is a excellent gunsmith in Centerville Indiana named Vern Trester. You should be able to find him on the Internet by putting in his name. He is one of the finest gunsmiths I have ever known and he has been smithing for years. Hope that helps! I would let a competent Gunsmith work on the pistol if it was mine. As you know they have not made them for some years now. That is a nice pistol. How is the bore?
