Honestly, I would put in a call to the local police and ask them about the shop.
?
Speaking as someone who believes very strongly in gun control and even more strongly in taxing the living daylights out of bullets at the point of sale:
Why would you call the police about a business that has a legal right to operate? What would you expect them to do?
To the OP: I think this is a personal decision you have to make. Think about your concerns and discuss them with your husband. What's his opinion? Then do some research about your concerns if necessary (e.g. if you're worried about someone buying a gun and going on a shooting spree, find out how many gun crimes are committed immediately after the criminal buys a gun).
