I go.to NH every so often and was wondering about CCW there. I know it's a constitutional carry state but does that mean I can just bring my pistol and carry? Do I need to have taken a CCW course before doing so?

Anyone except someone who is prohibited from owning firearms is allowed to carry a concealed weapon in New Hampshire without the need for a permit.  From the state's website:

So it isn't necasary to have taken the NH CCW class?

Who offers a NH class?

I got mine before I took the FL/AZ class... in which we were told to apply for the NH to get Pennsylvania (back when it worked). There is not a class requirement for the NH permit. It’s a form and check... that’s it.

You can always get the permit... as it works with states with agreements with NH. But isn’t needed... you can carry as long as you aren’t prohibited from possessing firearms.
