That would be an interesting data point. The one thing you would have to find out is which stores have FFL licenses and which don't. Not all chain stores sell firearms. I would also be curious to see where these stores are distributed geographically. EDIT: Right after writing that I saw this article http://www.citylab.com/crime/2016/01/map-gun-dealers-starbucks/423801/ http://www.citylab.com/crime/2016/01/map-gun-dealers-starbuc... While not exactly what I was looking for it is an interesting comparison.
