the ar15 in 223/556 is probably the best choice for home defense in a dense urban environment since the round is the least likely to penetrate more than one wall. most pistol rounds including the 380acp will go through walls easily as will shotguns.
the reason police use the ar15 a LOT is because it has a very good record of not being an overpenetrator when hitting humans dwellings and cars.
