I corresponded with a friend of mine that works at one of the big box outdoor retailers that previously required you to register concealable firearms before you could leave with them. He was not speaking in an official capacity and both he and the store shall remain nameless.
However, he said that you are now allowed to leave the store with a purchased concealable weapon without registering it with the city first. However, he got the impression that the city still thinks you need to register a concealable weapon if you are going to carry it within the city limits (assuming you have a CCP).
Omaha just doesn't get it. LB 817 specifically states: 18-1703 Cities and villages shall not have the power to regulate the ownership, possession, or transportation of a concealed handgun ....
Admittedly, this is hearsay so take it with a grain of salt.
