Seriously, the problem is this:
If a round disintegrates on impact with anything (like drywall), it's the equivalent of snake shot at close range, i.e. not so good for self-defense against a determined attacker who is about to kill you.
If it doesn't disintegrate on impact with anything, it's going to go through walls.
OC spray might be a better option, or a Taser, backed up with a gun, loaded with real bullets, just in case.
