firstelk hunter...
You can see that some guys have a pretty different view on this. I personally don't pack heat when bow hunting... But I do if I am packing Stock. Personally I am more worried about gettign my head kicked in by a mule with a broken leg than mauled by a bear. that being said, my buddy always packs a gun. and like i said, I do sometimes as well. It makes him feel better so that is fine with me.
By the way. I Have been "charged" by a bear while elk hunting. I believe he was looking for a meal, as I was in the middle of a heard of elk, trying to call in a big bull. I was not super intrested in killing the bear and figured it was possible that he was not looking for an elk or me to eat. I decided he could walk if he did not come towards me when I cow called...... he came and I mean fast. I drew my bow the instant he started at me from 30 yards and shot him at about 5 feet. one blade clipped his chin and the arrow came out just under his butthole. I stepped to the side and he crashed right by me, and fell about 10 feet past me.... not sure i could have done it any faster with a pistol. I mean what are you going to do walk around hunting with a cocked and locked pistol all day? sure it is possible but I got enough elk calls, binos, range finder, water bottles, gps, raido, wind indicators on and on already hanging off my pack. I am just not affraid of the dark or what comes out after dark. Don't get me wrong, I have a healthy dose of respect for those critters, but I don't sit around wondering if one is going to jump out from behind evry log. it is just not the case.
If you decide to pack a gun, my advice is to shoot solid hard cast bullets. Not hollow points. yes the Hp will do some damage, but not even a small % of the penetration. and if you just gotta shoot something that is eating you, it will likely not be a good shot, and penetration and or bone breaking is what you are after in that case. Hollow points are for shooting people.
I have killed big bears with a 357, 44 mag, and a 45 auto. I know for a fact that a 357 with a solid will penetrate a bears skull if shot from the side at point blank range while chewing on you buddies leg. I also know that a 45 auto with a solid will break the shoulder of a bear from 10 yards. though not an ideal round, you can put a lot of lead down range in a hurry. point is, that it will likely change the mind of a bear or what ever from wanting to bite you anymore.
good luck.
