So I've seen this a few times in the American Rifleman magazine.

I can think of a few good uses for these, but the second I start watching the video they have on their website, the "GIMMICK!!!!" red flags start popping up left and right. They show a few different guns stuck to the roof of a car in ridiculous positions. I'll give them the benefit of the doubt and assume they are just showing how the magnet will hold the gun, and not actually suggesting people drive around with the muzzle of a revolver stuck to their roof in the car.
My question is more along the lines of if this will hurt a gun or not. I know that if you stick a metal onto a magnet, it becomes magnetized itself. I don't really want a magnetic gun, but would this potentially affect the performance of the gun?
For the record, I'm thinking this might give me some more options to have my night stand gun more readily available to me, while at the same time, keeping it out of reach of my toddler daughter. Right now I have my night stand gun in my bedside gun safe, but that can be slow. I realize that I could just as easily put a high shelf on the wall, but the magnet seems like it'd be a little more versatile.
Also, I had thought about something for the car, but in the case of an accident, my loaded pistol is the last thing I need flying around my passenger compartment.
What do you guys think? Oh yeah, they also seem pretty damn pricey to me.
