I don't know how hard the newer ones are put on. Years ago I took the barrel off an old 3 screw Super and it wasn't very tight. Used to be that Ruger would switch a barrel very inexpensively. Also you could send them a ratty gun for rebluing and get back something that looked better than new, at a really cheap price. But before doing anything see how it shoots as-is.....may work just fine.
