I live in Kodiak AK, most of the biggest Brown bears in the world come from this island and I have seen my fair share including sticking one at a distance of less than 10 yards with my Mathews Switchback XT and having it charge me and stop approx. 4 feet from me and stare me down no lie. I almost shot it in the head with my .460 Smith and Wesson. I have done alot of testing with this gun and can say it is versatile in the aspect of being able to chamber the .45 Colt round, 454 Casul and also the .460. When plincking I shoot the .45 Colt when hunting, fishing, or hiking I chamber with .460 Corbon 395gr. Hard Cast Lead, no worries what so ever about it's stopping power, the gun is available in long barrel version or 5" barrel for packing, my #1 Choice goes to the Smith and Wesson .460, just my 2cents. Anything smaller you might as well use on yourself when the bear is eating you for lunch!
This selection/choice probably the best on IMHO.
To RESPECTFULLY ADD to the above, and
no personal slam intended regarding bow hunting........
Anything less than a 44 magnum, on any bear, you better be a damn good shot, and you better plan on emptying it in the vitals to stop them if they decide you are on the menu. I am talking in the throat, the eyes/mouth/nose, or base of the neck. Forget breaking any bones, which idealy is what you want to do in addition to taking out the vitals. You want to be able to disable the skeletal capabilities for them to get at you, I.E. a broadside shot, breaking the front shoulder(s) to put them down, possibly the spine to disable the hind quarters as well. The only handguns that are gonna do that reliably and consistently are 44 mag and above, and with the 44 mag you better do it right. Big, heavy, hard and fast bullets.
NOT FOR AMETEURS!
I have seen bear hunters drop a black bear from a tree with an "eye" shot using a 357 magnum, and yeah, a 9 mm might do the job, but it was a small bear, 250#, UNLIKE a 6 to 15 hundred pound brown or grizzly, AND there were 12 ga shotguns w/slugs and 30-30 and above rifles on hand backing up the handgun shot.
I have a video from a hunting program on T.V.. These LUNATICS were hunting grizzly w/a bow and arrow. Now again, they had two guys backing w/firearms, one had TWO long guns, a 12 ga w/slugs, AND a 338 magnum, cant remember either winchester, or remington ultra-mag. The other guy had a 7mm magnum. Well, the archer hit the bear a little too far back behind the shoulder, it ran off into the scrub. They started in after it, but it was getting dark, so they quit for the night, and followed up the following morning. They went 30 yards further than they were the night before into the scrub and the party was on. The bear was on the ground facing them, then lept up charging and they expended 3 slugs and a couple 338's to put it down, the guy w/ the 7mm never got a shot off, it happened that quickly. Now the video was taken after the incident, the guy on the program told the story as they were panning and filming the area, and the guide from Alsaka, STILL had not calmed down. Even HE was shook up.
You go into Alsaka and get attacked by a bear, you better be damn good w/that handgun, and it better be 44 mag or larger, if I had a choice, it would be larger. No way in hell would I have the stones to hunt a grizzly or brown w/a stick and a rubber band.
