I shot DA revolvers for years. I had never fired a SA revolver before my first cowboy match. My match revolvers are New Vaqueros with the standard "plowhandle" grip. It took me a while to get comfortable with them.
Earlier this year I bought a Bisley Blackhawk; it's built on the same cylinder frame as the New Vaquero but it has a very different feel. To me it feels more like a DA revolver with target stocks.
I have a friend who swears by the Ruger Bisleys for heavy loads.
