I came into a three inch M65-2 last week. I traded a couple of polymer pistols for it. Since they are always easily replaced and I've wanted a three inch, HB, fixed sight K frame for quite some time, I as very happy. This revolver has recessed chambers but the barrel is not pinned. The previous owner stated that it is a "transitional model"...That is of only moderate interest to me since I have no box with it and got it to carry and shoot. It is in nearly perfect condition and has been fired very little, if at all. It came with some S&W combat "banana" stocks but ther appear to be frankengrips with one type of wood on one panel and another on the other so I pulled a set of factory Magnas from the 70's out of my box-o-stocks...This gun is not a LE trade in. There is a "CS" stamped on the inside of the crane but I assume it's just an assembly number...Your new revolver is a nice find and I would be just as happy with a M64. I doubt my 65 will see any magnums as long as I have it...Congratulations!
