My girlfriend and I share an apartment. Our hours don't always line up together, and she is frequently by herself. She has the combination to my safe, and knows how to use my pistols. My question is this: In the event that, God forbid, she should need to use one of my guns, are there any laws stating that she cant use the guns that belong to me? She is legally able to own a firearm (no criminal record period), she just simply doesn't have any guns of her own. Just curious if anyone has any insight. Thanks!
