thanks, after wandering around I found this
What is Colorado's Out of State Permit Reciprocity?
A permit to carry a concealed weapon that is issued to a person (who is at least 21 years of age) by another state will be considered valid in Colorado if the other state, in turn, recognized Colorado's concealed handgun permits. [C.R.S. 18-12-105.6]
Check Colorado's reciprocity with other states.
NC honor's CO , so I'm good to go.
