I cut my teeth on revolvers back in the 70's carried one my whole NYPD career. I've seen them break, I've seen them malfunction. Good thing we had excellent guys at the NYPD range to fix our problems and boo boos. A good qualified S&W armorer will fix you up and get your model 60 back up and running good as new. A couple of months ago my 686-3 had some issues, went to visit Frank Glenn, he had me back up and running in about 20 minutes. I'll work on my 1911s, but the inner guts of a revolver is like trying to read latin.
