You've made a couple of good points so far (shot size and ear muffs).
The NRA published a study they did a few years ago that number 7 or 7 1/2 shot would stop anybody within a room size area, and would not penetrate the other side of a drywall wall. I just read about keeping muffs with your gun, to minimize your disorientation after the gunshots. I've got to do that myself.

Ear muffs?
It doesn’t make sense to handicap yourself by eliminating one of your best advantages in a low-light/high stress situation.
