what are ya'lls idea of a survival gun?, i have narrowed my selection to two. i have a 12 gauge pump with a pistol grip and forarm that is short and which packs a punch for self defense and critter gittin but is a little heavy. but i've also got a bolt action 22lr rifle, it would get small game ok and its light but self defense against larger critters would be iffy. i have a 22lr/22mag pistol, but i would need to be close and i see it only as a back up weapon. whats ya'll idea?, now i do own several more weapons including single barrel shotguns which are lighter but multiple shots are a good thing on a survival gun. i'm talking about a gun to overall do all that needs to get done to survive. i know there are trade offs for each type weapon, but which gives the overall best help to a person?, thanks.
