First rule of CCW CARRIERS when pulled over, KEEP YOUR HANDS ON STEERING WHEEL. Tell officer each move you intend to make, do it slow. I had retired police as CCW instructors.
When pulled over, do not do a lot of shuffling around in the car, like getting registration out of glove box, etc.
If night, turn on car dome lights.
If rear windows are tinted roll them down.
Keep your hands on the steering wheel.
When the officer asks you to do something, tell him what you are going to do in response.
Move slowly.
Do your best to answer his questions directly but without incriminating yourself.
I have been pulled over a few time in the last 20 years but have always ended up with just a warning, having done the stuff above.
