6.5" 610 shooting 40's and a 22/45 are probably the most enjoyable. They are about polar opposites, but when new shooters shoot with me they always come back to those two and want to shoot them again.
Lately I've been enjoying the heck out of shooting a .22 LCR as fast as possible from 10 yards. I'm not a speed shooter or in any way "trained" but I think throwing 8 rounds through that short barreled revolver as fast as possible has improved my shooting with all handguns.
