Default Bear? I'll take the.....

I'll take the 10mm. Brown or Grizzly? DEFINITELY the 10mm, if not bigger.

Kind of quietens all of the "it will bounce right off the skull" comments huh? Granted this is still a simulation. And at the right angle, you can make a bullet bounce off a plastic yard sign (I have done it). So as in real estate, a shot is all about location, location, and angle of entry.

For bear the 9 and 10 are both marginal so whichever you shoot better is your best bet. My choice would be an 870 with slugs and if not that I will defer to my 500 magnum.

I would say 9x19 is marginal when it comes to black bears and not adequate for any larger species of bear. 10mm Auto would be a much better choice for any bear defense, but still less capable than 41 or 44 Magnum.

Just like people bears can be of various sizes within breeds/species. Also of varying temperament even if cubs aren't part of the problem. The local black bears are fluffy, but generally about man size. Shot placement, shot placement and sufficient penetration are your friends.

If we're talking grizzly, I think I'd avoid handguns.

Neither. I’ve seen Bear shake off much much larger calibers. Even though it was temporary, they still had enough time to eat you.

I'd want something heavier than either the 9mm or 10mm ...if it were for defense against bear .

....if you can make a brain shot at a charging bear; and you probably WON'T. So for me the bigger gun the better. After all, we aren't all Bella Twin, you know.

If I were to choose any 9 mm weapon for bear defense it would be at the very least a rifle in either .35 Remington or .358 Winchester. Preferably a .35 Whelen, or possibly a 9x57 Mauser.

For anything the size of an adult bear a 9mm is, at best, marginal and probably sub-marginal. A properly loaded 10mm is in the same general range as a .41 magnum and unless you are going up against a large polar bear it would probably do the job if you can hit with it. Bears are a lot "thicker" than a human and have heavy bones. Getting into a spot that will shut a bear down quickly with a 9 mm is a questionable endeavor.

The friends and family in Alaska carry a 12 gauge shotgun with slugs and a Glock 20 (10mm) loaded with buffalo bore hard cast bullets — when going fishing . The 15 round Glock is thought of as backup and carried across the chest. A 9mm would be considered a bad joke.

A 9mm is quite capable of saving your life in a bear attack, just shoot your buddy, then run like hell.

The only 9mm I'd feel comfortable carrying for Bear Defense is the variety with ".357" in its name.

I'm aware that Bears have been successfully dropped by everything including .22LR — it's almost as if they're made of flesh and blood or something — but I'm an advocate for carrying the most powerful firearm which can be quickly deployed and fired accurately if you're headed into bear country.

So personally, I wouldn't carry a 9mm, heck I wouldn't be completely comfortable carrying a .40 either, despite the fact that it's my favorite cartridge.

If I were headed into the woods then I would either pack my H&K USP45 Elite loaded with Buffalo Bore 230gr .45 Super FMJ or my Mossberg 590 Shockwave loaded with Brenneke Black Magic Magnum Slugs.

When it comes to something as dangerous as a bear, don't mess around with what can work, choose what absolutely WILL work!

Granted, if 9mm is all you have to work with, then go with it, but at least get the hottest loads you can find and use solid ammo, no JHPs!

Let's go with real world experience if possible.

Surprised 9mm did so well, but i would trust 16 rounds of 10mm over 18 rounds of 9mm. Also if i ran into the 2-legged critter that needed shooting, i can hit them at 100yards much easier with 10mm than any of my 9mm's.
