Adverse scenario games are always fun.
Had I been given a choice I'd never primarily chose any hand gun for bear defense - and would pick exactly what you (or the guy in the pict) is holding. There is a reason it's the guide gun of choice. People left the thread question and went off in this direction.
A much tougher game to my mind is the classic - "you can only have 1 calibre to do everything with".
We get the occasional black bear, they aren't a problem. I'm in Mountain lion country and they take out livestock forcing you into confrontation with them.
I know, its just a technicality.. and Godwin's corollary applies after any post receives more than 10 replies.

or as they say, the best gun to use is the one you have with you.
