Dunno much about NFA's as you call them (I still call them class III's) but have toyed with the idea of owning one for decades. If and when I do own one it will likely spend it's life in a good safe and will be useless for HD, but I have 18" shotguns and trusted handguns for that. I can live without the raised eyebrows from the grand jury and local leo's as well. I'm more concerned about an unsecured NFA falling into the wrong hands than I am about being undergunned by home invaders. If tomorrow a band of SOF's kicks down my door with firepower superior to what I have at hand I'll chalk it up to bad Karma and do the best I can.
