Alright guys, lots of good responses. Appreciate it.
I will be living in my apartment alone (no roommate), and do not generally party much at all. I do socialize with people and whatnot, but rarely do I go to parties - never really liked them much.
The area I'm living in is not a horrible area in terms of crime, but at night it can definitely get pretty sketchy. Was actually followed by a group of people a few weeks ago who I'm 99% sure had bad intentions. I was lucky to find a group of people before anything bad happened, but that only reinforced my reasoning for wanting to bring my guns.
Of course, despite relaying this to her, she still thinks I'm paranoid.
The good news is I think she can be swayed in some way, which is why I'm asking this. She's generally pretty open to things I do (legal of course), so long as I don't do things irresponsibly. This is one of the few things she's really been difficult to deal with on. I told her I would invest in a gun safe to store my guns in, and I think this calmed her a little, but she's still very anti-gun and sometimes makes little remarks that bother me.
Worst case, the gun range I shoot at here (I rent the guns - they have a great selection for only $5 to rent them) has a walk in safe that they let you store your guns at for a small fee. The whole "I'll keep them there if I don't need them" idea sounds like a good one if all else fails.
I'm not planning on ruining my family or education here, just hoping that I can find a way to sway her without that even being an issue.
PS: Sadly, I don't think getting her to try shooting is going to work - she refuses to have anything to do with them. Convincing her take a gun class would be near impossible, much less having her go shooting with me. For a bit of context, she grew up in Taipei, Taiwan, where private gun ownership is basically non-existent. I can only imagine the anti-gun environment that she was probably exposed to - her sister is the same way.
