That's two!!!I'd go for a .357 revolver (Ruger GP100 maybe) and some sort of .22 long rifle
I guess to be sensible a rifle cal should be chosen, much as i would hate to be minus any handguns at all.
Like as not I would choose the AK, tho for better power and range my FAL is a great choice too. I'll stick with AK tho - plenty of that ammo around for most part, and the gun is on the whole pretty rugged.
