AR-15 with LOTS of ammo and probably a 9mm with LOTS of ammo. If this is truly a post apocalyptic state. You will have to fight to keep what you have and kill to get what you need!
Unless you have a reliable team of men that are heavily armed, adequate supplies to survive and a defensible location. In that case, life will be a large improvement over wandering around as a lone target.
