I would carry both but I would reach for the bear spray first...no doubt.

You guys poo- pooing paranoia over the nice, cute, harmless blackies will probably be correct the first 99 times or so. And then your gonna get chewed on. To the question- 10mm at a minimum, spray is for tourists. A potential "situation" can often be resolved at a distance with a firearm and a warning shot. Stuff happens pretty quick inside of 30 feet with a can of spray.

Agree 110%
