welcome to the the forum?
to gain a bit of clarification to assist in discussion, why would you believe/feel any specific holster would be 'illegal' while carrying a firearm?
further, where did this tidbit of information, e.g.' LE, acquaintance, CHP instructor, another site, etc., which led to you believing/feeling any specific holster would be 'forbidden by law' in the state of NC?
are you concerned your holster might be 'illegal' when you open carry (OC) or when you conceal carry CC in the tarheel state?
again welcome
