$20 and 1 week (usually) - can't beat that with a stick.
Just a little update, yes it is legal to open carry in NH, depending on the town you go to depends on how much the police will make a big deal out of it, a.k.a, go to Mason, and your probably not going to be bothered, pretty gun freindly, go to Manchester and expect to be, at a minimum, have a cruiser or two drive by you, if not a full out right stop and questioning. Bigger cities kind of frown on it, but won't, or should say can't stop you from doing it. A loaded anything in your car is a big No No, the bullets MUST BE out of the gun and stored away from the gun, with regards to a revolver, with a semi-auto, the magazine MUST BE unloaded, out of the gun ( this is a grey area, some say it is ok to have an empty magazine in the gun, some say it is not, I heir on the side of caution and remove it as to avoid confusion), and seperate from the bullets with out the proper non-res permit, you will have the book thrown at you for this, they seem very strict on this in all parts of NH. No loaded rifles, or shotguns at any time, permit or not. As far as the permit, the one week wait is not accurate right now at least, it has been 12+ weeks and still waiting, for both my wife and I, and they are pretty back logged, some in part due to the mass amounts of applications being submited, and the staffing cuts they have had to endure. Right now, seems this is going to be the standard as far as wait times, for the time being. I would assume, it will improve once they are able to catch up, since the election of BO, things have been a little off tilt with all the new firearms owners, first timers, re-ups, and converts. That is one primary reason you see high gun and ammo prices everywhere, is the severe demand for both, because of the new administration and some of the possible and likely new laws,rules and regulations that may be imposed on people. That is another topic all together.
In short; with out the NH non-res permit, OC is fine. No transporting a loaded firearm with out the non-res permit in your car. Apply for the permit so you can CC, takes no time at all to fill out, just the waiting period sucks right now.
