I think a manual is several pages of mfg liability stuff like "Always wear eyes and ears" "Don't point it here or there" "Lock it up when not in use" etc. Then it goes on to describe how the bullets go in one end and when you pull the thingie right there, they come out the other end.
I've never owned a S&W with a frame lock so I don't know what that part might cover. But I can't really imagine there's anything earth shattering in a revolver owner's manual.
Am I missing anything?
