A semi auto 10mm just has to be a part of everyone's protection no matter what, because even if your big bore rifle or handgun didn't do their job during the initial attack, then you can still empty the 15 round mag into the bear with a one handed grip while it's trying to claw and bite you body parts.... you surely couldn't miss at that close range. You can do a lot of shooting during those seconds of remaining life. If those 15 rounds didn't stop it... then you could simply say... Yes, Lord, I did my best... here I come.
