Oregon had to fight just to make it legal to carry a sidearm during bow season. Or, rather, to convince O. Fish snd Wildlife that only the legislature could make rules about carrying firearms. Pre-emption. Gotta read the regs. I’m guessing that the odds of running into a grizzly were kinda remote. A 10mm seems like minimum effort, and no excuse for not having it in a holster. Live and learn...if you live.
I think I see the problem. It's Oregon. Without doing the research, I would guess that Wyoming has more reasonable game and gun laws.
