Well, for sure:
12 gauge pump shotgun - Probably longer barrel for better hunting...
.22LR rifle - personal choice - I like my Marlin bolt action.. but they are all about the same

Then your third arm is up in the air... But handguns are good for personal defense... I'd go .45 revolver

Of course a 5.56 AR would be a good option... can't go wrong there

But a .308 or 30-06 hunting rifle with a x4 scope would probably be a more practical bet.
