I would be inclined to go with the 2 1/2 inch 686 Plus. It's well balanced, light enough for all day carry in a good holster, and that short barrel will be loud enough to scare away most predators.

BTW, I have determined that longer barrels are distinctly quieter than short barrels. With a 2 1/2 inch barrel and a full house 357, the result will be a damned LOUD handgun, make sure you have ear protection handy when carrying it. Otherwise, your ears WILL be ringing.
