Guns for sale are displayed at Maxon Shooter's Supplies in Des Plaines, Ill., Tuesday, June 25, 2024. A new national divide is emerging among states over whether to track sales by gun stores. A California law taking effect Monday will require credit card networks to provide banks with special retail codes to assign to gun stores. By contrast, new laws taking effect in Georgia, Iowa, Tennessee and Wyoming will prohibit the use of special gun shop codes in financial transactions. A total of 17 states have passed some sort of limit on category codes for gun retailers, while California has been joined by Colorado and New York. (AP Photo/Teresa Crawford)
