The requirement that written notification on juvenile handgun possession be given to a non-licensee to whom a handgun is delivered applies to all Federal firearms licensees. It applies to the return of handguns to their owners, as well as to their sale. Thus, a gunsmith who repairs or customizes a non-licensee’s handgun must provide the notification to the non-licensee when the handgun is returned. The sign posting requirement also applies to gunsmiths, unless the gunsmith only disposes of handguns to non-licensees who do not appear at the gunsmith’s licensed premises, for example, when repaired handguns are shipped to non-licensees.
