I have a shelf I'd like to stash a pistol under. Looking for opinions, experiences and intel about the various magnets out there for this purpose. Good ones vs junk of course, problems, etc. But mainly I want to know where to get one, places that have them in stock. I don't want to order one blindly, I don't do Amazon - I'm an old coot that prefers to look things over in person whenever I can.

Any input?
