For self defense wandering around town I carry either a j frame or a 2" lcr, stoked with wadcutters, and critical defense lite for reloads, only because the point makes it easier to reload if needed. Same load when camping, but I use WWB then because they are a little hotter than the run of the mill WC, but without getting to the hot loads. I carry that because a) not all hollow points are guaranteed to open 100% of the time out of a short barrel (wadcutters ALWAYS cut a .38 sized hole); b) they aint that expensive and are comfortable to practice with, and IMHO you SHOULD practice with what you carry; c) for me they are controllable and I am accurate. If I am camping, depending on where, I pack a 357, either a 60 3" or a 66 2.75" with 142gr flat nose, or hornady black either in 125 or 140gr XTP. That should take care of two legged and a lot of 4 legged varmints. I don't have any big bears around here; an occasional small black bear but they mostly run. (also carry bear spray). Hell, just the sound of a 357 out of a 3" barrel is obnoxious enough to drive most anything away.
Some camp grounds don't allow carry, they say, but the snubby is ALWAYS in my pocket and the WWB wadcutters should suffice most of the time IF NEEDED. But the Maggie isn't too far away.
FWIW, I carry a revolver because the first round, maybe 2, are snake shot. Just in case. And I like to shoot them more than a semi.
I will also admit sometimes camping I am packing a Ruger Wrangler, but again with snake shot the first (or two).
