Ruger® 10/22 Takedown® Autoloading Rifle Models
Good little 22 that breaks down into smaller parts.
Carry your pistol for defense, pack the 22 for hunting. (sling the AR for rock-n-roll time)
Also, 22 ammo is cheap and easier to carry 1000 rounds of than say 9mm, .45, or 223.
I second this - should be in any bag.
adding that the pistol may be better for defense in quick reaction close quarters - but the .22 rifle could be more useful to secure your shelter. If one or the other, I'd rather have the Rifle. More uses.
