Indiana has enacted state preemption of firearm laws. However, local laws passed before 1994 or for certain narrowly defined emergency situations are valid. East Chicago, Gary and South Bend all have local laws that still apply. Governing units may restrict firearms possession on public property. Additionally, private businesses may also restrict (or forbid) firearms on their properties.
Indiana is a "shall issue" state for the License to carry a handgun. The Indiana license to carry allows both open and concealed carry. Most Indiana residents confuse the license to carry a handgun with a CCW. A license to carry will be issued to individuals age 18 or older who meet a number of legal requirements. Grounds for disqualification include a conviction for a felony or for misdemeanor domestic battery. A license can also be denied if the applicant has been arrested for a violent crime and "a court has found probable cause to believe that the person committed the offense charged". Documented substance abuse is a disqualifier, as is documented evidence of any given person's "propensity for violent or emotionally unstable conduct."
Application for a license must be made to the local police department, or absent that to the county police department. Four-year and lifetime permits are issued for Indiana residents. Out-of-state residents may only be issued four-year permits.
It is illegal to carry a concealed weapon, even sporting arms, on school property or on a school bus, on an airplane or in the controlled section of an airport, on a riverboat gambling cruise, or at the Indiana State Fair. Lawful gun owners may have guns in their vehicles on school property provided the driver is only transporting someone to, or from, a school event.
Indiana honors CCW licenses issued by every state (Illinois and Wisconsin do not issue CCW licenses), generally including non-resident licenses. However, Indiana residents, or non-residents with a "regular place of business" in Indiana, must obtain an Indiana license.
Firearms dealers or private individuals may not sell any firearm to someone less than 18 years old, or less than 23 years old if the buyer was "adjudicated a delinquent child for an act that would be a felony if committed by an adult", or to a person who is mentally incompetent or is a drug or alcohol abuser. Possession of automatic weapons by individuals or dealers who have obtained the appropriate federal license is permitted.
Short barreled shotguns (barrels under 18", OAL less than 26" length), are prohibited.
Handgun cartridges that have "a projectile that has a metal core and an outer coating of plastic" are prohibited.
Indiana law stands mute vis-à-vis long gun carry. There are some Department of Natural Resources rules, but these only apply on DNR property. Generally speaking, possession of long guns is legal whether the gun is either on one's person or in one's vehicle, loaded or not.
Indiana provides lawsuit protection to law abiding manufacturers, sellers, and trade associations for the misuse of firearms by third parties. Lawsuits are permitted for cases of damage or injury caused by defective firearms or ammunition, or breach of contract or warranty.
