It is hard to say what the best shtf guns are since we really do not know what the situation will be. If you are facing unruly mobs or gangs you will need firepower. If the population is decimated and you are surviving, there are totally different needs. On the run you need light weight and stealth. One pair of guns is not going to do it all. Unless you are in a group, you wont be taking big game and snares or traps would be a good solution. Husband and wife or a team should have matching weapons so there is interchangeability.
