I have bought four guns in my life, two rifles and two handguns, and have never been delayed.
My wife has bought two guns in her life, one rifle & one handgun, no delays.
Now my FIL has bought two guns, one rifle & one handgun. Delayed both times from two different stores. He was in the Army for four years, has never had any Felony's and he can't understand why he gets delayed both times he has made a purchase. But he is a post man.
Does anyone know if your occupation has anything to do with buying a firearm?
