If heavy loads are'nt in the probalbe picture, you really just gotta decide between sing;le action and double action. Make that choice and you've got your answer.
Keep in mind something, if you're to buy brnd new, the current production Ruger Blackahwks that are blued will have the internal lock and black plastic grips. No big deal to me but a cursed feature to some. You might be able to locate one of the .41 Acusport Bisleys and a recnet warehouse cleaning put a small amount of regular Bisley .41's on the market. There's also the .41 Hunter which Davidson's contracted. The non-Bisley model is still easily found. Just some other options to consider.
Regarding Taurus, I'd avoid unless you want issues that won't be taken care of.
