I can't say as I disagree with the idea of using a carbine for home defense. I do disagree with the fact that people think it's too much for in a home. There is frangible ammunition available for civilian purchase that addresses the 'over-penetration' issue. Besides, if there's an intruder in your home and the cops get called, you can dang-well bet that there'll be at least one of the cops armed with some kind of a carbine too. Their ammunition isn't frangible!!
