Curious if anyone here has a BMW E60 5-series and has found some concealable, lockable storage inside the cabin for their handgun?

The slim lock boxes that a lot of people mount to a seat rail (under the driver's seat) don't seem to work, as there's really no space to fit something there, so I'm curious if someone has found a better solution? Thanks in advance.It would be to fit a J-frame revolver or a S&W Shield compact.Would like to avoid trunk storage, as that means I'd be always having to look around and make sure the coast is clear when unholstering. via /r/CCW http://ift.tt/2l5jZzx
