I'm on my way to TN. I have done my homework for getting a TN HCP. They don't do CCW. From what I can tell its just a matter of presenting the state my CO CCW permit and paying them $50 for a transfer of some sorts. I see I have to notify my county in CO (Jefferson) of an address change within 30 days. I am assuming I will have to go through some sort of background check, fingerprint , etc in TN and wait for approval. It may take 60-90 days from what I hear. During this time is my CO CCW not valid? Will I have a window of no CC? Anyone know? Anyone gone through this sort of thing?
