The title says it, don't complicate it, just YOUR top three survival arms for where you are.

No limit to what you can have, but your top three and why.

Growing up in the midwest, rifles weren't legal for deer hunting, so my choices for back there reflect that.
Ruger 10/22.
Remington 870 or Mossberg 500 in 20ga with the spare deer barrel that has rifle sights. Home defense and hunting but doesn't beat up my shoulder.
And last but certainly not least, a Ruger Mk1 with the 5.5" target…

Pick your go to survival three pack.
