well this is a topic I have seen posted and asked countless times on many forums, over the yrs
the .45 acp, VS Bears
and the majority of folks will say this, its NOT the best caliber to use on bears period!
your better off buying another gun, more suited IMO
that said, IMO< the deal comes down to this and it applies to larger calibers as well
its SHOT placement period to a degree
HOW great a shot are you when a animal is charging at you
think your precise and accurate?
as if not, then IMO< it comes down to two things,
1 you want a larger caliber that has some extra energy and shock values to MAYBE slow or stop a charge(and most charges are bluff charges too by the way)
2, a gun you can shoot MANY rounds REALLY FAST and mostly accurately!
everyone THINKS there a pro shooter till something BAD happens and then, maybe they realize there NOT as good as they brag about being or THINK they are
so its time to be really honest!
about every animal in the world has been killed with a .22
this doesn't make it a GOOD choice for big game, but YEs its killed a lot of it,
when conditions are right and all things line up, it will kill
but the point is, do you want to have extra power for when things DON"T go perfect
Bear spray is proven to work VERY well on bears too by the way, but few folks feel as tuff as they do holding a can of it over a gun!
NEXT< MY issue with a 1911 and GOOD Bear type ammo
is, well, its really Hard on your 1911 unless you changing springs to help save the gun from some extra power good bear round give off when being fired
are you also going to spend the $$ to buy a bunch of the ammo to practice with and get good at both ihtting what your aiming at, and handling the new recoil the rounds will give off, and knowing your gun will function well with them!
as for rounds to thin about, these get my vote

again, I would suggest a better bear like gun, if carrying a gun is in your plans in bear country, call it an investment
a cheap small shotgun loaded with good slugs is a cheap option too, can be had for what few boxes of good 45 acp ammo will run you too if you buy used!
