It's one thing to have a gun and keep it in your car, but your delivering pizza's to 99.9% of the time to familys or people who just want food, I don't think I would be safe if I answered the door payed the pizza driver and as he walked away, saw a gun strapped to his pants or tucked into his pants. who's to say he's not impersonating a pizza driver or if you didn't tip him enough if he will get upset.

So many things could go wrong with a driver carrying a weapon. I could see having one with you on your way from the building you work in to your car, but I don't see why you would need to carry one while delivering pizza's.
