I came across this beautiful modified S&W revolver but I cant figure out from what model it is made? There is no text on the barrel which indicates a shortened barrel. The caliber is most likely .38 Special but it could also be a .357 magnum. I didnt have any .357 so I could see if they fit. There is a large S&W logo on the other side of the frame. What is your take on this model and how much is modified by the user and how old is the revolver?
