Omaha PD FAQ: Who is required to register concealable firearms with the CIty of Omaha/Omaha Police Department?
Omaha Municipal Code 20-251 requires that all concealable [handguns] inside the city limits of Omaha be registered. Regardless of where a person resides, concealable firearms inside the city of Omaha are required to be registered with the Omaha Police Department.
Persons whom [sic] are valid Nebraska CCW permit holders (or any other State which Nebraska has reciprocity with) are not required to register firearms and can be in possession of concealable firearms which are not registered.
=====================================================
The bad news is that if your end destination is Omaha, you cannot legally bring that handgun into the city limits of Omaha unless you immediately go to the Omaha Police Department station at 15th and Howard to register it. There is no grace period.
If your end destination is not Omaha, but you are passing through to another end destination where the handgun is totally legal, then federal handgun transport law applies [18USC922a] and you would be covered by federal transportation rules. You might get busted by OPD anyhow; they might still defy federal law by writing a summons and confiscating your handgun. It happens.
Should you choose not to register the handgun as above, my recommendation would be to:
-Remove all ammunition from magazine and chamber
-Field strip the handgun
-Install cable locks through the barrel and magazine well
-Put those parts in a lockable case
-Lock the case
-Put the case in your trunk under the spare tire
-Give away the ammunition
[After all the above, the unregistered handgun is still illegal in Omaha; these steps will help your attorney help you in court.]
Further:
-Drive very carefully while you are in Omaha
-Do not mention anything at all about any handgun if you are stopped in Omaha.
Does all the above seem a bit ridiculous?? Yes. But you are in Omaha, which has one of the strictest municipal handgun codes you'll find anywhere.
Welcome to the Big O. We're actually Pretty Nice People. [Except for a coupla draconian handgun laws.]
