but davey crocket killed him a bear, when he was only three.
Personally I don't see why a Grizzly would need a 9mm
the Grizzley didn't
need the 9mm, he just took it from the last guy.
seriously though, this whole "handgun for bears" thing that comes up every month (or twice a week) is silly. even in Alaska, bear attacks are less common than moose attacks. I don't think you need to pick a gun specifically for bear defence. my advice is to take a gun that works against humans, which are the most likely to give you trouble.
Bears are big, with a slow metabolism. a grizz bear's heart beats about once every 8 seconds. They are also very fast. 30mph fast. Even if you had a .50BMG derringer or the "roger rabbit" revolver or whatever and completely destroyed a bear's heart, it could still cover 40 yards and play pinata with you for a while before it becomes incapacitated. you aren't going to stop a bear charge, even with a rifle, unless you break bones, preferrably spine or pelvis.
yes, people hunt bears with handguns. but in a hunt is an
offensive operation: hunter shoots the bear, it runs away (or tries to), hunter tracks it to where it died. the main point is that the bear didn't initiate the attack, it's caught by surprise. in a
defensive situation, If the bear attacks, it has the advantage because it has already decided not to run away. however, any wound or loud noise might be enough to change it's mind and convince it to run away. and if it didn't attack, well in that case you don't need to defend, eh?
In they unlikely event that you are attacked by a bear, whatever gun you have with you will be fine. I've never heard a (credible) story of someone that shot a bear with a handgun* and was mauled anyway. The gun you have with you, the one that you
will carry, is the right one for bear (or any other kind of) defense.
(although i am sure we'll see 100 posts about someone's uncle's friend, etc. and how you just
have to carry a 5 or 6 pound handgun like a Raging Bull or Deasert Eagle .50 and so on)
* (but I know of one case of a hunter hiting a bear twice with his .280 rifle and being killed anyway)
oh, and I suggest you wear rubber underwear too, because you are more likely to get struck by lightning. be prepared for any possibility, right?
p.s. what's the best handgun for defense against walrus?
