Currently, approximately 31 states honor Indiana's handgun licenses. Although the Indiana State Police does not track this specific information, organizations such as the NRA, and websites such as http://www.handgunlaw.us/ do attempt to track reciprocity. When in doubt, always contact the agency of authority in the specific state to which, or through which, you are traveling.
