I own a handful of NFA items and I use a suppressed on my home defense gun. I am not married, have no kids, and no roommates so my bedside gun is not kept under lock and key. But my girlfriend has started to stay over at my house more and more often, including sometimes when I am not home. Is allowing her unsupervised access to my suppressor illegal? All the other guns and nfa items are locked up in a safe that she doesn't have access to. All the items were done under individual, if that matters. If it is illegal, I assume the only two options would be to lock them up every time I'm not home or get a trust and add both of us to it. Let me know if this thread would be better suited for the legal section.
