Felon firearm possession questions
Questions about whether a person “can own a gun” often hide several separate legal issues: ownership versus possession, federal versus state law, actual versus constructive possession, ammunition, the legal effect of a prior conviction, and whether later relief changes the result.
Restoration questions
Restoration can involve state law, executive clemency, post-conviction relief, correction of an erroneous record, or federal relief under 18 U.S.C. § 925(c). There is no single national restoration form that resolves every state and federal disability.
