There's usually several different law enforcement agencies that can be contacted to double check on each other's opinions & advice.
There's local, county & state. There might even be a separate office for pistol licensing that can shed some light even further.
Then there are state gun organizations that have members and staff more familiar with the intricacies of their state's gun laws.
Lastly there are firearms lawyers. It's always better to check and double check about grey legal areas before any possibility of arrest rather than after it becomes too late.
