A .357 is an adequate caliber for most black bear and a lot of brown. It starts getting mild when you get to larger bears. How serious are you at carrying? Go with a 2" Ruger SP101 if you will carry often Or a 4" GP 100 if occasional. Both are concealable, the smaller one is a bit easier to conceal.
Buy some 180 FP CoreBons for the bears and some standard 125-158 hollow points for the "social" carry.
Get some training in defensive shooting.
