I have a protective order against the abuser. Can s/he keep a gun or buy a new gun?
There is nothing specific in Mississippi's laws that would make it illegal for a person who has a protective order against him/her to possess a firearm. The law does not specifically authorize a judge in a protective order case to order the abuser's firearms to be surrendered.1 In addition, having a protective order against you would not disqualify you from qualifying for a license to carry a concealed handgun.2
However, federal laws, which apply to all states, restrict a person's right to have a gun under certain circumstances, including when there is an order of protection that was issued after notice to the abuser and a hearing. Go to Federal Gun Laws to get more information.
