Give ~ Glock welcome to NC's world of OC'g as well as to the forum...
to assist you in your quest, here is the NC's attorney general's little brochure:
http://www.ncdoj.gov/getdoc/32344299...-gun-Laws.aspx (section III is of import)
as well as where the NC's statutes are located along with the handy search function in the upper right side:
http://www.ncleg.net/gascripts/statutes/statutes.asp
now as you peruse these documents, you will fail to locate anything regarding statutes granting permission to OC'g in NC since there are none listed, and it makes NC a gold model for it's citizens to OC as they go about their daily life's.
of course there are caveats on OC'g, such as on educational property, etc. but your attention is directed to the brochure for specifics where no firearms are allowed, CC'd or OC'd.
section III of the AG's brochure is of import as it provides guidance regarding carry of a firearm in a vehicle~ there are no statutes covering specifics.
as is my custom, I always end with suggesting individuals take a firearm course, from an unbiased instructor such as the NRA's basic pistol course.
as to your friend, i would smile, keep the training funds and the money you are bout to pay to the sheriff, and smile knowing saved a couple of bucks.
as to your carrying a glock, i am sorry for your misfortune...:shocker:
BC, as JimC said: Ah, you are so much more than kind, you can keep the dime."
