Got to disagree with you about the judge. ruger has come out with this item in a 7.5" barrel. In the case of a HD situation, these rugers can handle heavy hot loads along with assorted scatter shot. Tactically, .410 munitions can be designed to fit a wide variety of situations. For instance, the intruder is wearing a armored vest. And your judge is packing drive-pin sabots. The vest is easily penetrated. Or you really dont want to kill the intruder. But, instead set'em on fire. There are incindiary munitions in the .410 caliber also.
Depends upon the situation. Home defense is just that. Short range hold your ground. And make sure they can't get there head up. Blast away.
