I personally like gun shops that have their firearms displayed out where customers can freely handle and inspect them at will.

That said, though, I couldn't count the times I've been browsing the racks in a gun shop and seen customers pick a gun up off the rack, shoulder it, sight down the barrel, pull the trigger, and then hear the sound of the firing pin dropping where someone else cocked it and left it that way.

This led me to think just how easy it would be for some over the top anti-gun/animal rights zealot, or your run-of-the-mill nut case to sneak a live round in one or more firearms when displayed in that manner.
