Go with the carbine for HD. Make it a .223. AR, AK, Daewoo, hell, even the Kel-Tec SU-16 if you're strapped for cash. The .223. only overpenetrates with FMJ. When 55-62 grain soft points hit sheet rock, they fragment like hell. FBI did a study on it, then our SWAT guys (i'm a cop) actually re-tested FBi's data at the range and got the same results. We're ditching the MP-5s for our entry team and equipping them with 11.5" ARs.
