You do not have to meet Mississippi’s residency requirement to apply for a concealed weapon permit if you are serving, are an honorably discharged veteran, or are a retired service member.
Apply for a Mississippi concealed weapon permit through the Department of Public Safety and give them your proof of service and of your handgun training.
Your military ID, DD214 or retirement paperwork, and documentation of your law enforcement or combat training with pistols or other handguns.
