Next September I will be doing a solo hunt in eastern AK for 10 days. I'm getting dropped in by my pilot-friend and I don't plan to see another human until he comes in to get me or something I kill. I will likely be bringing both my S&W 329PD and a can of Counter Assault. I definitely don't ever want to shoot a bear in self-defense, but will if necessary. The spray is probably great for a nuisance bear or one that just persists in hanging around. Don't discount that kind of danger. I recall reading about a guide who got badly ass-kicked by a grizzly they had seen many times in the area of camp. They even had that bear nicknamed and considered him just a potential nuisance. He nailed the guide and it ended badly as I recall.
One personal thing for me: My handgun and bear spray both have tethers attached. In the heat of an encounter it's very easy to trip, fall or get knocked around and subsequently lose your grip on what might save your life. A piece of neon orange 540 paracord between the gun/spray and holster works well. Call me an over-thinker, but I plan to survive with as few scars as possible.
Finally...when I
know I'm going into dangerous country I go with a partner, and he looks like this:
