A concealed weapon is defined as a firearm or dangerous weapon that is concealed if it is carried in such a manner as to not be discernible by the ordinary observation of a passerby. The only way to legally carry a concealed weapon in North Dakota is to apply for and receive a concealed weapon's permit issued through the Chief of the Bureau of Criminal Investigation. The applicant, however, will need to have a valid reason for carrying the firearm or dangerous weapon concealed. For further information visit the Bureau of Criminal Investigation's website.
