I never do. At least not since the 80's.
When I got my first cc license here in NH sometime in the 80s I asked the lady behind the desk, "What do I do if I'm pulled over and am wearing my gun? She said, "if you are pulled over, keep both hands on the steering wheel and when the officer arrives at your window tell him that you are wearing a gun and am a licensed carrier? Okay.....sound good.
A month or so later I'm on my way to the range, 45 holstered on my right hip when a State Trooper picks up on my inspection sticker and pulls me over. I do exactly as the dispatcher told me. When the officer arrived at my window I say, "Sir, I want to inform you that I have a loaded pistol on my right hip and that I'm a Licen....
Back then the state cops carried 357's. I know because right about the time I said Licen...I had one pointed at me.
This is a very uncomfortable feeling when you can look out of your left eye and see 6 hollow points looking at you from about 24 inches away.
Although I have to say that the officer, after that point handled everything very professionally.
He had me place both my arms out the window and told me that he was going to open my door and told me to slide out keeping my hands out the window. Once out, he unholstered my 45 and unloaded it and everything was cool after that. He actually became quite friendly...Although he did give me a ticket.
But to make a long story short... I never, since that day wear my sidearm while in my car.
In NH you don't have to tell a police officer if you have a gun on you. But since 1980 something, if one ask me, "Do you have a firearm with you?" My answer is,
"I am a licensed concealed carrier vetted by my chief of police but I do not have a firearm with me at this time....Sir.
If he ask, "Is there a firearm in the vehicle my answer is the same... With a smile of course.
And thats only if one ask...If he/she doesn't ask I dont say shit about it.
What say ye?
