I am looking for a small S&W revolver for potential concealed carry. I do not have a carry permit yet (in process) but I do have my TWIC card. TWIC is the ID needed to work port security and requires strict background verification annually. It is an approved form of government ID. I also have a valid OR ID. I would prefer a m637 but will be happy with m638, m642, m60, etc. Have cash in hand in the Portland area.
