Can’t find fault in your reasoning. Having never been in that situation (bear or enormous animal assault) I can only armchair postulate, but the mechanical operation of a pistol *may* be a wink link compared to a revolver. Hear me out…..one may, under stress, limp wrist that 10mm, and hoo-boy that may be a problem, whereas a revolver won’t suffer that problem. Same problem if the bear is on top of you…it could be jammed with blood and gore and said bear may still have enough oomph to bite down on your melon. Just a thought. I think I’ll stick to my revolver for a purely self-defense platform in dangerous places, per my aforementioned logic. Now if I was to hunt over a bait pile, a 10mm is worth thinking about.
