As a side note, a few years back, before I obtained my CCW, I purchased a pistol in Omaha. The seller (a shop) would not release the weapon to me until I had registered it with OPD.
So, you pay for it, take the paperwork to OPD, then take the registration back to the seller and pick up the weapon.
This is why that was and will remain the only weapon I have purchased within the Omaha city limits. Besides, there are many sellers outside of Omaha but in the metro area, including one who occasionally posts here, that I prefer to go to.
