A shotgun is one of the best overall defense guns for the SHTF situation. They are simple to operate and sturdy. You can use it for defense, and you can hunt all manner of game with it (bird shot, buck shot, slugs).
I'd think a 20" barrel should be fine for most things. In the academy we shot Remington 870's with a 14" barrel and nothing but a ramp bead front sight at a range of 50 yards and got good hits on man-sized targets (00 buck).
I would add an extended magazine tube, though.
