Only one? Are we talking SHTF street survival, or lost in the woods survival?
SHTF street survival would be my Mini-14 with a good supply of ammo.
Lost in the woods, If I knew ahead of time I was going to be lost in the woods, I would take along a shotgun with a variety of ammo, for taking birds, deer, pigs, whatever. But then again if I had my wife along to tell me which way to turn, I never would have gotten lost in the first place.
