Guns, Dogs and Blades QnA

OK, if you have a 12 gauge and a fullsize pistol in 9mm, would you say that's enough to defend, or what would you get next?

Smaller handgun for conceal carry or a rifle for hunting and distance self-defense? I don't hunt, but I can if I have to in SHTF mode... and I'm getting a vibe. If a rifle, recommendations?

Or my favorite, just put the money into getting the old Valiant on the road?

Thanks!
