The Best Prepper Guns List – Must Have Weapons for SHTF -

Pretty standard.

For the shotgun, I'd go with the AA-12, although any of the pump varities will provide good overall service.

Prefer the AK platform over the AR for close in rifle work.

Desert Eagle in the 45 cal with a 38 or (the completely under rated) 22 cal as back up.

Long rifle, if I had my druthers, any Weatherby with a 308 cal or larger. For me, the later is just a pipe dream.
