Summary

• Permit required: No,  for most adults Maine is a permitless/constitutional carry state for concealed handguns.

• Minimum age: 21+ to carry concealed without a permit; 18+ allowed only for active-duty/honorably discharged military, and 18–20-year-olds otherwise need a permit.

• Duty to inform:Partial. Required only if carrying concealedwithout a permit during a law-enforcement stop/detention/arrest.

• Where you can/can’t carry: Generally allowed in most public places, but banned in places like courthouses, schools, many state parks, federal buildings, posted private property, and certain posted bars/restaurants.

Maine allowspermitless concealed carry of handguns statewide for people who can legally possess firearms. The permitless rule is uniform across Maine, but theoptional concealed handgun permit system still exists for those who want reciprocity or to carry in certain special locations. 

Permits are issued by either theMaine State Police orlocal police departments/municipal authorities, depending on where you live. Maine is effectively ashall-issue state for permits: if you meet statutory requirements (age, background checks, training, etc.), the issuing authority “shall” issue the permit. 

Maine recognizes many out-of-state resident permits for reciprocity, and it also issuesnon-resident permits. Even though a permit isn’t required for most people 21+, having one can expand where you may carry (e.g., certain state parks) and helps when traveling to states that honor Maine permits. Visitors should double-check reciprocity and local posted restrictions. When transporting or storing a firearm in vehicles, hotels, or other shared spaces, follow safe practices: keep itsecurely stored, control access, and consider using aFaraday-protected SLNT bag alongside a lockbox to discreetly secure valuables and electronics that may be stored with or near your gear.
