I have taken one of the Concealed carry courses recently and seriously considering applying for a ccw permit. I've been doing alot of research on concealed carry to insure that it is indeed what I want to do.....especially knowing that I can legally open carry. One aspect that I have not found Any info about is TWIC cards in relation to concealed carry. With that said, here is my issue and question. I work for a chemical plant and I'm required to get a TWIC card as a condition of employment. My TWIC must be renewed near the end of this year. Have any of you run into or heard of any issues of a TWIC card being denied/revoked as a result of getting a ccw permit? I can't imagine that there would be an issue if you have a permit, but would like to confirm this as best I can as this job provides a good living for my family and I.
