I'm not a lwyer and am not giving legal advice.
License, registration, and proof of insurance is all you are requred to show.
When officer approaches, hands on the wheel where he can see them, or sticking out the window. When searching for paperwork, move slowly and tell him what you are doing.
If asked about guns, simply don't respond or say "nothing illegal" or something along those lines.
Under no case do they have the right to enter the vehicle or search any external compartments without a warrent or probable cause unless you expressly give them permission.
If asked to leave the vehicle, ask if you are under arrest or being detained. If he answers in the affirmative, ask what the charges are and say you are invooking the 5th amendment and want a lawyer. If he won't answer contine asking if you are under arrest or if you are free to leave.
I don't see anything wrong with this approach but I believe that some stater\s require you to state that you have a hand gun and ccw. You can go to www.atlantictacticalfirearmstraining.com and they have a link so you can review each states firearms and conceal carry laws before you go in.
