As long as the individuals involved are legally able to own a firearm, private sales can occur between individuals. With that being said, there are prohibitions on who exactly can own a firearm in the state.
In accordance with IN Code § 35-47-2-3(h), a person is not legally permitted to own or purchase a firearm in the state if the person:
has been convicted of a felony;
has had a license to carry a handgun suspended, unless the person’s license has been reinstated;
is under eighteen (18) years of age;
is under twenty-three (23) years of age if the person has been adjudicated a delinquent child for an act that would be a felony if committed by an adult;
has been arrested for a Class A or Class B felony for an offense committed before July 1, 2014, for a Level 1, Level 2, Level 3, or Level 4 felony for an offense committed after June 30, 2014, or any other felony that was committed while armed with a deadly weapon or that involved the use of violence, if a court has found probable cause to believe that the person committed the offense charged; or is prohibited by federal law from possessing or receiving firearms under 18 U.S.C. 922(g).
Residents of Indiana are not required to register their firearms with the state. This is in direct contrast to the laws of many states.
If an individual wants to conceal a firearm and carry it about, there are specific license requirements they must meet.
They must be at least eighteen years old before they can apply for a license
There is an online application that must be filled out on the Indiana state police website
They must then submit their fingerprints via a registered fingerprinting station
A background check will be performed and they will be required to pass
After the fingerprints have been taken, the applicant must visit a local police department with their application number and the requisite fee within 90 days. The application expires within 180 days.
If an individual was granted a license in another state and is not a resident of Indiana then it will be recognized by the state of Indiana.
