I love this thread. It's kinda funny because it hasn't even decended to the "no, what you really need is a cocked and locked 1911 with 230grn hydra-shocks" level. I guess I'd part with some half-way useful knowledge rather than being sarcastic or talking out of my @ss.
I live in black bear country and have seen some mean, nasty, persistant bears. I've never killed one, except for sport. A friend of mine carries a "customized" "short barrelled" semi-auto 12 with a pistol grip when he goes camping. I'm not sure, but I think it's a mossy. Either way, it's incredibly painfull to shoot, but it's the RIGHT weapon for bear defenSe. Load with slugs and 000 buck. It's maneuverable enough and when empty, serves as a better club than a 9.
