Windows down, interior lights ON as appropriate to lighting conditions. Permit, Operator's License, Insurance and Registration IN YOUR HAND on the top of the steering wheel.
"Officer/Deputy/Trooper....I just want to let you know, I have my permit and I am carrying. It is (give location here). What would you like me to do now?"
What you do NOT say is, no matter how reasonably...."I have a gun".
What you have done is politely inform the officer without ever saying "gun" or "concealed weapon" which to a rookie can sound like "I GOT A GUN!", that you are legally armed and are merely sharing information in a way that is non threatening, even to a wet nose boot on his first solo patrol shift.
Yes, you may live in a state where there is no duty to inform. I don't care. Inform the officer. It does not hurt you, harm you, cause manginal issues, and early manstruation, or a violation of your rights. What it does do is give the officer the first piece of the puzzle of information that you are a "card carrying good guy" and puts the entire contact on a much more friendly footing.
When I was in patrol, on those rare occasions that I would actually pull someone over for a traffic violation, if the driver informed me in close to the above manner, my answer was "Great, thanks for letting me know. I appreciate it. If you don't play with yours, I won't have to play with mine".
If there were no Wants or Warrants, and their DL, INS, and REG were good I would end the contact with "I pulled you over tonight because you have a tail light out (or whatever minor infraction). Why don't you hit the 24 hour AutoZone up the road and get it fixed before someone writes you a ticket".
"You mean you're not gonna write me a ticket?" was the usual response.
Mine was "No, why make your day longer? A busted tail light is not a major crime wave, just get it handled".
See, I figured a working man/woman who in all likelihood honestly didn't know that they had a minor equipment violation also didn't need a piece of paper to tell them that they had an adult chore to accomplish. So, if they were cool with me, and informed me that they were carrying instead of making it a surprise, then I would then reciprocate their attitude and be cool like Fonzie and cut breaks when I could. I had other crime and **** to deal with.
No, I didn't cut breaks on outright sheer stupidity that disregarded public safety, such as DUI, or reckless driving...but little ****...why be a dick?
So...inform the officer...don't be a dick...and more often than not, your lack of being a dick will be reciprocated.
