It sounds like somebody is setting up the perfect gun case. Once the city has permitted every aspect of selling guns EXCEPT for selling handguns, it would be a slam-dunk to simply start selling handguns and dare the city to act. The Supreme Court has explicitly protected the right to own a handgun in the home for self-defense. It's not going to be permissible to outlaw the sale of such arms, given that a business has jumped through all the other hoops.
Exactamundo.
