Alex...
My Tracker 627 is a .357. I have a Weigand mount on a S&W 617 that is already tapped. I would like to use the Taurus made 10-034 mount that will attach to the rib without drilling but they have been out of stock for a long time. If I can't find one I guess I will have to use the Weigand and have the Tracker tapped. I am hoping there is someone out there that has a 10-034 they would like to sell or know where I can get one.
