Inski, I have a stack of those too. If it's easier you can get one from me.
My girlfriend is a officer here in Lewiston. Although declaring might be a good ideain ways, it's not leagally required. I think it's gonna come down to situation. If I'm getting pulled over for speed or minor infraction, and it's concealed on my body as it should be, it's my business. I'm breaking no laws. If the officer asks me to step out of the car they may pat me down, then I'll mention it as to not catch the office off guard. Or if I have it on the seat or in the glovebox then I'll mention it only if I have to go there. I also keep all my info on my visor so I don't EVER have to dig for it.
My permit was issued in Lewiston, so LPD and other androscoggin cops using the same computer system can see I have a permit. It comes up on their screen as an extra tab when they run my license.
I just chose to not make more of a situation then need be. I'm legal to carry, if it doesn't effect the situation then don't bring it up. But keep your hands on the wheel and away from it. Why run the chance of being pulled out of a car on the side of a road for nothing. You have to understand the most cops are supporters of conceal carry.
That's my 2 cents.
