I have found this thread very interesting. I only know of one person who has any NFA weapons. He doesn't keep one for HD. His reason was that he isn't willing to risk a 10K gun for some skimeball to get the drop on him. As much as we train, the BG's could split up or something. I figured that sbr's and sbs's wouldn't be put under as much scrunity from prosecutors or investigators. I have actually thought of getting a shotgun and converting it to a SBS for a HD weapon.
I would imagine that no matter what you use defending your person or home. That item will be taken by investigators until it is determined that your actions were justified. It wouldn't matter if it was a full - auto or the wife's cast iron skillet.
