I have a Rohn 22 revolver (looks like a single action but it is actually double action). Piece of junk. Only thing it is good for is as a dummy for practicing spinning or fast draw (unloaded of course) because it is steel so it has roughly the right weight and balance and you won't give a crap if you drop it.
. I haven't fired it since I got my Single Six. I am waiting for a "gun buyback" program where they will give me some cash for it.
