Louisiana is a "shall issue" state for concealed carry. The Louisiana Department of Public Safety and Corrections shall issue a concealed handgun permit to qualified applicants, after performing an NICS background check and giving the local police 10 days to provide additional information about the applicant. An applicant must demonstrate handgun proficiency by taking a training course from an approved instructor, or by having been trained while serving in the military. Concealed carry is not permitted in any portion of the permitted area of an establishment that has been granted a class A-General retail permit, to sell alcoholic beverages for consumption on the premises, or in any place of worship, government meeting place, courthouse, police station, polling place, parade, or in certain other locations.[3][4][5]
Open carry of firearms in Louisiana is permitted without a permit, as long as the user is of at least 17 years of age and legally able to possess a firearm under state and federal law.[6]
