New Hampshire is a pretty good state for it's gun laws and as a LEO here I will only say this; I have more important things to do than worry about who has a CCW permit because if you've made it through the process of getting it, chances are you are a decent law-abiding fellow. But this is NH, and every state is different with required notification, posting on your drivers lic., etc.
How do I feel about dealing with CCW permit holders?? I love it. They are always respectul, forthright, and easy to deal with, partially because in NH it can be taken away as easily as it was issued in the event of a problem, and review by the issuing authority. I can tell you for a fact that our permits, other than the standard background check, never leave the PD. They don't get forwarded to the State Police, they don't go to the FBI, ATF or otherwise. They stay in house and locked in the Chief's files. Re-up in four years. If you move from the community that issued the permit you need to advise the PD of the community that you moved TO if still in NH. Really just a formality and not a big deal.
I wouldn't worry so much about it my friend.
