I live in a house with 3 other guys - all unfortunately not firearm saavy and reject requests to learn how to use them. (Side Note: I can't believe I found these people in TEXAS!). Anyways, I keep my 9mm chambered at night, but pop out the round and throw on a lock when I'm gone during the day. All of the other guns are locked up. Just rotate the rounds to avoid loading one cartridge too many times and occasionally take your defensive ammo to the range and shoot it out for some new stuff.
