For what it's worth, I just ended up buying the Stack-- On QAS-103
Amazon.com: Stack-On QAS-1304 Low Profile Quick Access Safe with Electronic Lock
to use as a bedside safe. Bolted to the nightstand, it won't be easy to bounce, and being electronic (with a key in case the battery dies), easy-open at night.
I just plan on replacing the batteries when I replace the ones in the smoke detectors.
It's worked well for me, as I've done several (unloaded) dry-runs in accessing my glock from both in bed and out.
