If the threat involves the risk of death or serious injury, the person can use deadly force in self-defense.
Note: Since this article, restoration of firearms rights may be possible for person who has been adjudicated as a mental defective or who has been committed to a mental institution under recent legislation. See Restoration of Firearm Rights After Judicial Commitment blog for details.
