Get a couple of those rare earth magnets (like the coin-sized ones) and Gorilla glue them to the underside of the dash. They are unobtrusive so your wife doesn't see them, but when you're driving, you can attach your firearm to them by the slide, or glue a second set to a holster and attach that. I know it doesn't sound solid enough to hold a firearm, but I've seen people do it, those magnets are really strong, and if you use 2-4 of them, I'll bet you can get a really solid mount. Google it and you'll see several tutorials.

I've thought about it, in my Tahoe I keep my Glock in the driver's door pocket, but I would like to move it. In my Z, it slides under the driver's seat, but it doesn't stay there if I am driving in a... spirited manner.
