I have never fired a .32/20, haven't even seen one. I do have an SP-101 in .327 Federal. Fixed sights, short barrel though. If Ruger would get off their duffs and chamber a 50th Anniversary Flattop (small frame) in .327 Federal with a 7 1/2 inch barrel this discussion might be moot. Of course you would still have the brass problem, but I can't imagine 32/20 brass is easy to find unless Starline makes it. Nothing that hasn't been said before, I am sure.
