You're sub leasing an apartment from a friend of yours. Her boyfriend is known to be a violent person and has threatened to physically harm you and your significant other multiple times. You ignore the threats and he shows up at your door in the middle of the night with a few other guys with him. He has a key for the apartment that he got from his girlfriend (since the apt is in her name, she would have a key) so he was able to let himself and his friends in. You wake up to physical threats from three men in your home.
You have you pistol within arms reach from your bed, but out of sight. Its fully loaded.
What do you do?
