Under 18 U.S.C. § 922(d), it is unlawful for any person to sell or otherwise dispose of any firearm or ammunition to any person knowing or having reasonable cause to believe that such person “has been adjudicated as a mental defective or has been committed to any mental institution.”

A license to carry concealed handguns must be issued by the Department of Public Safety (DPS), pursuant to section 45-9-101(2), if the applicant:
Has not been adjudicated mentally incompetent, or has waited five years from the date of his or her restoration of mental capacity by court order;
Has not been voluntarily or involuntarily committed to a mental institution or mental health treatment facility unless he or she possesses a certificate from a psychiatrist licensed in Mississippi stating that he or she has not suffered from disability for a period of five years.

A person is ineligible for a license to carry a concealed weapon if the person:
(1)  has been diagnosed by a licensed physician as suffering from a psychiatric disorder or condition that causes or is likely to cause substantial impairment in judgment, mood, perception, impulse control, or intellectual ability;
(2)  suffers from a psychiatric disorder or condition described by Subdivision (1) that: (A) is in remission but is reasonably likely to redevelop at a future time; or (B) requires continuous medical treatment to avoid redevelopment;
(3)  has been diagnosed by a licensed physician, determined by a review board or similar authority, or declared by a court to be incompetent to manage the person's own affairs; or
(4)  has entered in a criminal proceeding a plea of not guilty by reason of insanity.
 
The following constitutes evidence that a person has a psychiatric disorder or condition described by section (1), above:
(1)  involuntary psychiatric hospitalization;
(2)  psychiatric hospitalization;
(3)  inpatient or residential substance abuse treatment in the preceding five-year period;
(4)  diagnosis in the preceding five-year period by a licensed physician that the person is dependent on alcohol, a controlled substance, or a similar substance; or
(5)  diagnosis at any time by a licensed physician that the person suffers or has suffered from a psychiatric disorder or condition consisting of or relating to:
(A)  schizophrenia or delusional disorder;
(B)  bipolar disorder;
(C)  chronic dementia, whether caused by illness, brain defect, or brain injury;
(D)  dissociative identity disorder;
(E)  intermittent explosive disorder; or
(F)  antisocial personality disorder.

A person is barred from possessing, purchasing, receiving, attempting to purchase or receive, or having control or custody of any firearms if the person:
Has been admitted to a facility and is receiving in-patient treatment for a mental illness and the attending mental health professional opines that the patient is a danger to self or others. This prohibition applies even if the person has consented to the treatment, although the prohibition ends as soon as the patient is discharged from the facility;
Has been adjudicated to be a danger to others as a result of a mental disorder or mental illness or has been adjudicated to be a mentally disordered sex offender. This prohibition does not apply, however, if the court of adjudication issues, upon the individual’s release from treatment or at a later date, a certificate stating that the person may possess a firearm without endangering others;
Has been found not guilty by reason of insanity of enumerated violent felonies. A person who is found not guilty by reason of insanity of other crimes is barred from possessing firearms unless a court finds that the person has recovered his or her sanity;
Has been found mentally incompetent to stand trial, unless there is a subsequent finding that the person has become competent;
Is currently under a court-ordered conservatorship because he or she is gravely disabled as a result of a mental disorder or impaired by chronic alcoholism
 
A person shall not have in his or her possession or under his or her custody or control, or purchase or receive, or attempt to purchase or receive, any firearms whatsoever or any other deadly weapon for a period of six months whenever he or she communicates to a licensed psychotherapist a serious threat of physical violence against a reasonably identifiable victim or victims. Licensed psychotherapists are required to immediately report to a local law enforcement agency the identity of a person who has communicated a serious threat of violence against a reasonably identifiable victim or victims (see § 8105(c)).
