Gun law in the United States is defined by a number of state and federal statutes.  Sale or delivery of firearms is restricted in New Hampshire like any other U.S. state.  In almost all the states of the US, an importer, manufacturer, dealer or collector shall be licensed under the federal Gun Control Act of 1968 to be a lawful seller.

Any person who, without being licensed as herein provided, sells, advertises or exposes for sale, or has in his possession with intent to sell, pistols or revolvers shall be guilty of a class B felony.[i]  No person holding a license issued under the provisions of RSA 159:8 shall sell a pistol or revolver to a nonresident unless such nonresident has authority under the laws of the state of his residence to purchase them.[ii]  The attorney general annually, files with the secretary of state a summary of the laws of each state of the United States relative to the purchase of pistols and revolvers in such states.  The licensee may rely upon such summary in determining if a nonresident offering to purchase a pistol or revolver has authority.

Any person who sell or give to any minor any pistol or revolver shall be guilty of a misdemeanor under the laws of the state of his residence[iii].  However, this provision shall not apply to the following:

• Fathers, mothers, grandparents, guardians, administrators or executors who give a revolver to their children or wards or to heirs to an estate.
• Individuals instructing minors in the safe use of firearms during a supervised firearms training program, provided the minor’s parent or legal guardian has granted the minor permission to participate in such program.
• Licensed hunters accompanying a minor while lawfully taking wildlife.

Individuals supervising minors using firearms during a lawful shooting event or activity.[iv]
