I do not have an order of protection against the abuser, and s/he has not been convicted of any crimes. Can s/he have a gun?

Montana state laws do not have many restrictions on possessing a firearm other than those related to crimes and protection orders. However, there are additional restrictions when it comes to getting a permit to carry a concealed weapon that do not involve a conviction or a protection order. The applicant must:

  • be 18 or older;
  • be a United States citizen or permanent lawful resident;
  • have a valid Montana driver’s license or other form of photo identification issued by the state;
  • be a resident of the state for at least six months; 
  • not be ineligible under Montana law to own, possess, or receive a firearm;
  • not be ineligible under federal law to own, possess, or receive a firearm, which means the applicant cannot: 
    • be a fugitive from justice, meaning s/he fled any state to avoid being prosecuted or to avoid testifying in any criminal proceeding;
    • be an unlawful user of or addicted to drugs (controlled substances) - but this does not include alcohol or tobacco;
    • have been declared by a judge to be mentally incompetent or committed to a mental institution against his/her will;
    • have been found not guilty by reason of insanity or have undergone some other court proceeding about his/her mental illness;
    • be an immigrant who is illegally or unlawfully present in the U.S.; or
    • have given up (renounced) her/his citizenship to the U.S.;1
  • not have been charged and awaiting judgment in any state of crime that is punishable by incarceration for one year or more;
  • not have a warrant out for his/her arrest;
  • not have been adjudicated in a criminal or civil proceeding in any state or federal court to be an unlawful user of an intoxicating substance and not be under a court order of imprisonment or other incarceration, probation, suspended or deferred imposition of sentence, treatment or education, or other conditions of release or be otherwise under state supervision;
  • not have been adjudicated in a criminal or civil proceeding in any state or federal court to be mentally ill, mentally disordered, or mentally disabled and still be subject to a disposition order of that court; and
  • not have been dishonorably discharged from the United States armed forces.2

In addition, the sheriff can deny an applicant a permit to carry a concealed weapon if the sheriff has reasonable cause to believe that the applicant is mentally ill, mentally disordered, or mentally disabled or otherwise may be a threat to the peace and good order of the community to the extent that the applicant should not be allowed to carry a concealed weapon.3
