Keep in mind that I very much like single action revolvers. Long time participant in Cowboy Action events, as both a competitor and match director. When traveling to out of town matches I'd put full power ammo in them for nightstand use at the motel.
Having said that, I don't think anyone will argue with the notion that these firearms are outdated in design compared to today's offerings. Hard to ignore that if one is carrying their sidearm primarily for personal defense reasons.
