One of the things I always teach my students is do not advertise. We call it concealed carry for a reason. And frankly plastering all your pro gun stickers in the window and having a quick release fast draw rig attached to the tunnel or your dash just tells a bad guy to break your window as you very likely, may or may not have a firearm in the car and at the very least they can score some ammo or spare mags. All items they can turn into cash for the mere effort of breaking your window. On B side I have looked at those rigs a time or two and they seem pretty well thought out. I have yet to see one in the flesh tho.
