"I've been accussed of sometimes being over agressive when it comes to personal defense for myself and my family. ... Thats why I prefer 8 rounds instead of the usual 5 in a shotgun. ... I can get off eight rounds rather quickly and accuratley, drop the empty mag, and have 7 more rounds to go."
I wouldn't want to be your lawyer! Empty a high-capacity magazine at someone, and, heaven help you, reload another one and start firing it too, and you'll get ripped to shreds on the stand in court - a short stop on your route to jail for homicide. That's one reason why defensive training (as opposed to other kinds of firearms training) is so important. You have to be able to defend not just the fact of lethal force based on the circumstances, but how it's applied. Given that you're likely to have little or no actual rational thinking going on at the time of an incident, the training is going to have to take over on its own. Given how the courts rule these days, it better look something like a double tap and an attempt to get away. Everything you just described can be spun into premediation.
