OK, I am reading a great shtf book called Lights Out. it was wrote by a forum member on another board and I consider it to be as good as patriots. the subjects live in texas and in the book a firearms dealer is able to sell a guy guns that his his ccw without calling into whomever they have to call into to. Is this something made up for the book or is this info legit? if it is true, it doesn't apply in OK correct?
