Big or small, I like 'em all
When I first started shooting I thought revolvers would be awkward to hold and not comfortable at all. Then I tried one and it was like the clouds opened up and a beam of my own personal sunshine warmed my soul. Between my double action S&W's and single action cowboy guns in both cartridge and cap&ball black powder gun I've easily got more revolvers than I do semis.
For casual range fun a SA style can't be beat. The re-loading drill slows things down just enough to stretch out the fun while not becoming too much like work. Especialy if you are shooting bigger fun rounds such as magnums.
