I’m with you flier...., In the weeds,. Seriously since I didn’t see a specific SHTF; civil unrest or wilderness survival. If civil, for me I’ve got a custom bolt action pistol that is as quiet as it comes, for something that in my hands will get the job done out past what a bumper jack can reach. My wheel gun, though in my hands (Mecklek is beyond fast) not as fast as some, will keep the jackals from rushing me until I get my 590 in play. For survival would only need one, though would carry two. I reload so it didn’t matter how long it lasts, either way I’m in play until something else happens supplies isn’t what I’ll run out of first,. Targets perhaps.... Anything I don’t have either would be laying around or I won’t need.
Some old shooters will tell you that the best gun for a given situation is the one closest to you.
I think there’s a lot of wisdom in that.
