Ok, so from other threads I've learned that 32 ACP is just fine for bear defense... but on a more serious note, given the choice of the two, if hiking in bear country, would you prefer an M1A or some kind of "tactical" shotgun (minimum 8+1) with slugs or similar? What would your ammo choice be, respective to your selection? Or, do you think neither of these wouldn't be adequate with some of the larger varieties of bear? Wanna kill these ads? We can help!
