I used to have a setup like that only it was a 1911 in a holster. It was monted to the bedframe like that.
You could make one of those things rather easily out of some flat metal and a mig welder. That'd be a pretty neat project too... I like the idea, but I would prolly crap my pants when I wake up in the morning, roll out of bed all groggy and lay my nice warm legs on that cold gun steel!!! That's a rude awakening for sure.....
Anyone remember the pictures of my Gecko readin the forum? I got pics somewhere of him trying to get that dumb bug! It was so funny and I've actually thumbed it once or twice late at night.
