I floated this idea on here a couple of years ago and it did not go over well.
Because its silly and all firearms get damaged with the moving in and out of the show cases and the safe. You can always tell the stores that do that with the endless scratches on the finishes of the metal plastic and wood. And its not required to secure them in that manner.
A decent sized store could easily have hundreds of firearms to remove and install twice a day, the cost to do that and the damage to inventory make it a never ending loss.
