Last year, October 2022, I used my SD driver license with PMB address to purchase a 9mm at Fleet Farm in Rapid, no problem only waited less than 15 minutes for the thumbs up to make the purchase. This last Wednesday, April 19, 2023, I tried a small mom and pop shop in the town in South Dakota that I live in and just found out today, Saturday April 22nd, that I was denied. Not sure why and they were not able to get me the ATF number to call to find out why the denial. The only thing I can think of is I remember the guy at Fleet Farm in Rapid saying the PMB ID was ok but to make sure I file in a part of the computer application a certain way and at the mom and pop place it was a paper and ink application. Does anyone have an idea about about computer vs. paper and ink application in regards to applicants that have PMB on their license/ID? I haven't become a felon since last year and I hold a professional medical license in this state of South Dakota so kinda confused why this happened and pissed because small towns talk A LOT!! Thanks in advance!
