We really need a tacked bear thread.....
I've dealt with a lot of bears, mostly grizzly and browns, some blacks...With that said, the best weapon you can use is a shotgun with brenneke black magic slugs for a "stop it in its tracks bear gun"....Next to that a big African dangerous game cartridge like 505 Gibbs or a nitro express...Down from that is a quality hunting bullet(designed for penetration in a magnum rifle caliber suck as 375H&H, 460 Weatherby and such....Here is the problem with all of those choices..when you need it the most, it will most likely not be within arms reach..just a fact of life with any shotgun/rifle..they are just to big and to heavy to have on your person 24/7...
So that brings us to pistols and the much less powerful pistol cartridges...Sure you can carry a 500S&W, 454 casull, or any of the other hand cannon pistols...2 problems with that, First, they are both big and heavy, meaning just as with the rifle, they often get left off your person when needed most... Second and more important, to be charging bear proficient with any of them takes constant year round practice for most people..First, its very expensive to shoot one that much, second, very few people will dedicate themselves to it, and when that skill is needed most, most people aren't going to be able to make the shots they need to...
Next down on the list is some of the middle weight calibers, 44mag, 41 mag, 357..definitely much easier to stay competent with, a bit cheaper to shoot, and not so heavy that a person can't make themselves wear it 24/7...So a good compromise to all out power and needed accuracy in a cartable package..The revolvers do have one drawback and that is capacity, most or 5 or 6 rounds, a few have more.. If you read thru the article on bear attacks, it is more common then most people think to need more than 5 or 6 shots to end a bear encounter. Meaning if you need 5 or 6 rounds, you are now carrying a worthless club with very very little chance of getting it reloaded in time to further defend yourself....Maybe a bit better with moon clips versus loose cartridges, but definitely something a person needs to consider and have a plan for...
And that brings up the large frame auto's, most commonly the Glock 20, delta elite in 10mm or a 9mm/45acp semi auto pistols.... These are light enough to carry, they have the round capacity plus can quickly be reloaded, not much issue carrying 24/7, but they are light on power...The big advantage is they are most likely very close to what an average pistol people carry everyday, so familiarity and close to equal recoil/accuracy/dexterity with very little practice needed more than they already do.. A big risk with an semi auto pistol is limp wristing or pushing the muzzle up against the animal and ending up with a misfire..luckily its easily trained around and should be easy to avoid in the woods..A further issue is getting adequate penetration, but most of the semi autos will do just fine with a quality hard cast lead load such as underwoods 200 grain 10mm hard cast load..Most people with very little practice can easily get off multiple shots in a split seconds with a semi auto they can shoot good..
Reading the bear articles a person should come away with the idea that while you hope you can get "first shot stop a bear" with any weapon, many of the stories show great results with stopping the attack simply by getting multiple rounds on target, even if they are only minor wounds, they appear to often end the attack where one minor wound with a larger hand cannon may not end an attack..Nothing is going to be 100% every time, just not how the world works, but some careful, honest thought, practice and follow thru should allow most people to get thru a bear attack unscathed and healthy...whether that is with bear spray, a shotgun, DG rifle, or a pistol varient...I will say this from friends who have resorted to bear spray..many many times the spray is going to get you as much as it will the bear..Normally if the wind is from you to the bear, you will never see the bear let alone surprise him, hence why so many bear attacks are total surprises..the bear had no clue you were there until you were right on top of him...We carry spray, but I always get my firearm in hand first, then consider if bear spray is feasible(wind direction, bears attitude)....Every option has pro's and con's, up to you to decide which will work best for you...
