It depends what is in your backcountry. I carry a P229 in 40SW when bowhunting in MI, but we don't have any Grizzlies. Some little black bears and wolves are about the worst wild critters we run into, but in all reality the 4 day/year drunken territorial on public land ******* moronic "hunters" are probably more of a real threat. Like always, a few idiots cast us all in a bad light . . .
If I'm in Grizz country, I'd be packin at least a 44mag. Oh, and bear spray too
