Is Open Carry Legal in Montana After the 2026 Policy Reforms?

Yes, Montana generally permits open carry of firearms without a permit, aligning with state preemption laws that override local ordinances. However, recent 2026 legislative proposals may introduce municipal restrictions in urban centers like Billings or Missoula, necessitating compliance checks with county sheriff offices.


Key Regulations for Open Carry in Montana

  • State Preemption Enforcement: Montana Code Annotated § 45-8-351 prohibits local governments from regulating open carry beyond state statutes, though cities may impose temporary restrictions during declared emergencies under MCA § 7-3-2201.
  • Age and Location Restrictions: Open carry is lawful for individuals 18+ in most public spaces, but prohibited in federal facilities (e.g., national parks), schools (MCA § 45-8-361), and private property where posted.
  • Concealed Carry Distinction: While open carry is unrestricted, carrying a firearm concealed without a permit (MCA § 45-8-327) remains illegal unless exempt under the “permitless carry” statute (effective 2021).

Local Compliance Note: Counties such as Ravalli and Gallatin have historically enforced additional signage requirements in public buildings; verify with local sheriff departments for 2026 updates. Failure to comply with federal regulations (e.g., 18 U.S.C. § 930) in restricted areas may result in federal prosecution.
