Up until recently my thought process was: Buy what's legal, but if I choose to upgrade it with less legal but not insane additions (e.g. 19rd Glock mag instead of 10rd legal limit), so be it. If it's for home defense, I don't want to be impaired if the shit ever hits the fan.

But NOW: a friend took a class on local gun laws and said that even a totally straightforward, legal home defense shooting could cost you $100k in attorney fees just to ensure nothing goes sideways in the courts.

Now imagine if I used an illegal weapon (or an illegal component). Holy complications.

I'd be comfortable possessing a larger capacity mag to use at the range (legal as far as I understand), but, crazy as it seems, would try my best to only reach for the legal parts if someone breaks in.
