I use a small MicroVault safe that is secured with a cable. If you have a hydraulic bedroom slide, under the bed works very nicely by wrapping the cable around the slide mechanism frame. It our 3670, it also mounts, with some additional hardware, in the closet. Large enough for keeping the checkbook, extra cash/credit cards, and a Keltec P-11 or Ruger LCP. It will keep the opportunistic slimeball out, but a determined turdball, with tools, could probably get it out after a while. But then, they would not want me to come back and find them trying to remove it.
