personally I think a magnum revolver is ideal as your very unlikely to have the time to fire off more than 5-6 shots from any handgun if your charged is dependable firepower and a 357-44-500 mag packs a decent punch
ITS AS ALWAYS DEPENDENT ON YOUR PERSONAL SKILL LEVEL.( AND EQUIPMENT CHOICES)
FAST EXPANDING HOLLOW POINT BULLETS ARE A BAD OPTION.
notice they stated they had a great many body hits fail to penetrate the bears vitals with the handgun ammo being used.,
yes both the 10mm and 44 mag have been successfully used to kill bears and successfully used in self defense
keep in mind the PROJECTILE DESIGN IS CRITICAL as it does ALL THE WORK, and SHOT PLACEMENT is CRITICAL, simply because the projectile can't be effective if not placed where it can do the most damage.
you must also select a projectile designed to maximize results on its intended target thus you must know the intended targets anatomy and where the vitals are located internally, a bullet designed break bone and penetrate to the vitals on a large bear will zip through a human opponent, causing less than ideal internal damage, a bullet designed to max internal damage on a human opponent might expand far to rapidly on a BEAR! to ever reach the vitals!
but as always precise shot placement and a knowledge of bear anatomy is critical to rapid success.
445 dan wesson revolvers
YOULL NEED TO SHOOT A GREAT DEAL TO GET THE NECESSARY PRACTICE, its that frequent practice and hand loading that significantly reduces ammo cost, THAT MAKES THE 445 REALLY EFFECTIVE IN YOUR HANDS, CASTING YOUR OWN BULLETS SIZED EXACTLY TO THE THROAT/BORE SIZE HELPS, AS DOES THE COST SAVINGS...

44 mag reload info
one of the most effective and UNDER RATED revolver calibers is the 44 mag, and even the more the underrated 357 mag, now Id point out right off, that while both are lethal in experienced hands and .... that any hunting revolver will loose significant velocity with a barrel length of under 5"...

I was asked why I don.t own a ruger 480 handgun?
I was asked why I don't own a ruger 480 handgun? like many other people ,I think its a good pistol ,a darn good cartridge. but other options are marginally better in my case. I own a couple 44 mag revolvers, a 500 S&W, and a couple 445 DWSM revolvers, making owning a 480 ruger, a low...

vs recoil levels and the potential accuracy and number of shots capacity and much of that is related to the level of practice & experience the operator has.
glock 20/10mm with aftermarket barrel for more effective cast bullet use generally noticeably improved accuracy with hard cast
,Id point out , after reading years of reports, two basic facts are obvious,
your chance of being attacked or mauled is very very low,
and if attacked ,that in most cases you'll be forced into a very close range confrontation ,
under a very limited amount of time on a fast moving attacker,
Id doubt you'll have time to place more than 3 shot's maximum,
and your life might depend on the results of a single hits lethal damage.
personally Id prefer the 44 mag revolver with a 300 grain hard cast bullet over 21 grains of H110 powder,
but I would certainly not feel defenseless if all I had was a 10mm pistol,
there are 180-200 grain hard cast bullet loads over about 10 grains of blue dot, have worked well on hogs, and deer
(CHECK YOUR LOAD MANUAL)
keep in mind no handgun has near the stopping power of a 12 ga slug,
or a 45/70 or 450 marlin with a hard cast 400 grain bullet
keep in mind its a knowledge of the opponents anatomy,
your skill at accurately placing shots under stress,
and precise shot placement more than power or magazine capacity,
that makes ALL the difference

and if its properly loaded with heavy hard cast gas check bullets,
has a noticeable power advantage over a 10 mm handgun
consider the fact that your very un-likely to have time to get off more than 2-3 shots in a bear defense situation, a 41-44 mag revolver seems to potentially hold some advantages over a larger capacity 10mm semi auto.
yeah its mentally comforting to have a 15 shot mag capacity,
but only hits to the vitals count in stopping a bear attack!
below some 44 mag related info, notice hard cast 44 mag revolvers far out perform the typical 10mm,
but realistically if your going to be shooting in a defensive confrontation,
you'll be lucky if you can get off more than 2-3 reasonably well aimed shots,
so magazine capacity .
while mentally it might be comforting its all but meaningless under real conditions.
as a defensive cartridge a 10mm is in my opinion close to ideal for a human opponent,
but it is certainly a bit less effective on a bear that might be significantly larger and much more heavily muscled.
I recently read of a fishing guide that carried a glock 10mm,
who was mauled and killed in ALASKA ,
they found he never got off a shot because,
he had never chambered a cartridge,
and he died with a full magazine.
witnesses stated he was attacked at very close range ,
unexpectedly , he drew his pistol but never got off a shot
