Back-up for bear and Concealed Carry are kind of mutually exclusive. I guess if it were me (and I'm assuming you're talking about black bears), I'd get one of the various 1911's chambered in .45 acp. For carry, something in a Commander size (4" barrel") and probably an alloy frame for weight reduction. I don't particularly care for Glocks, as, for me, the grip angle is wrong, and they don't point as naturally as a 1911.
