Does anyone know of a gunsmith in the Triad area of North Carolina who could do a barrel swap on a M851. My M851 currently has a 4 inch barrel and I have a 3 inch I would like to have put on it. I checked with a couple of gunsmiths who said their jigs for S&W K Frame would not work to do a barrel change on the Rossi because the frame is smaller. I like my M851, but would like to have a 3 inch barrel on it if possible. Thanks. Here is a picture.
