Common practice for most people in the rare event that they've had contact with the police is to verbally give name and address (but not produce identification)
You are not required to produce identification during a consentual encounter with police. You are not even required to give your name and address. Whether you choose to do so is a personal decision.
Other things of note is to clearly state "I do not consent to any searches, I do not consent to any siezures" if they try to remove your firearm or search your person. They will laugh and do it anyway, but its important that you document that you denied permission to search.
Their search then becomes an illegal search and siezure (again, nothing you can do about it at the time, but later you can)
The reality is, its highly unlikely you will have any interaction at all with the police.
Relax, enjoy your freedom and post up how it went and where you went.
