I'm all for anything that keeps the officer safe and happy. They have a tough job.
And therefore, why tell him I have a gun? It's CONCEALED. He isn't going to see it. It seems the only time they are going to get excited is when you tell them you have a gun. Then they ask where it is, keep your hands away, give me the weapon, step out of the car, I have to run this number, etc. etc. etc.
If I am asked to get out of my vehicle then I will inform the officer I have a weapon and what would you like me to do with it?
I want the least amount of excitement I can get. If the officer doesn't know I have a weapon he isn't going to worry about it.
