Better to have something than nothing, there isn't a handgun that's adequate to stop a charging grizz with one shot without hitting grey matter, most rifles won't drop them in their tracks. Carry whatever your comfortable with, and keep a few prayers in the mag, if you have to pull a pistol on a charging grizzly, those prayers are your best bet. This is a long range hunting site, and we all know why we do everything we can to reduce recoil in our rifles...... It's so we can hit stuff with them. Same goes for handguns, but even worse, a flinch with a short barreled handgun can result in a miss by several feet when shooting at targets that are less than 20 yards away. I shoot as many or more rounds out of my handguns every year than I do my rifles and can assure you that it takes more practice to become a good shot with a pistol than it does a rifle. A long range rifle requires more technical knowledge, but a handgun requires more shots down range imo, I suppose some of that depends on what your naturally good at....but....I can hand my rifle to someone who has never shot one before and have them hit a plate at 200 yards the first time they pull the trigger, and then have the same person shoot a pistol at a refrigerator box at 20ft and miss the whole box. If you can shoot big handguns well, it's a great option for you......If you can't, let's face it....your bear food, so leave your 10mm at home and fill your pockets with berries so you taste good.
