Yes, Missouri is a constitutional carry state. Since January 1, 2017, when SB 656 took effect over the governor’s veto, adults who are at least 19 (or 18 with military service) have been able to carry a concealed firearm in most public places without a permit, provided they are not otherwise prohibited from possessing a gun. Open carry is also legal statewide without a permit, though cities and counties can regulate it for people who don’t hold a valid concealed carry permit.
Permitless carry removed the application requirement, not the rules. Missouri still bars certain people from carrying, still designates places where guns are off-limits, and still punishes violations. And in one important respect, going without the optional permit is riskier than holding one.
Who Can Carry Without a Permit
To carry concealed under Missouri’s permitless framework, you must be:
- At least 19 years old, or at least 18 if you are a current or honorably discharged member of the U.S. Armed Forces
- A U.S. citizen or lawful permanent resident
- Not a person prohibited from possessing firearms under state or federal law
No training, background check, or application is required. If you meet those criteria, you can carry.
Who Cannot Carry
Missouri’s unlawful use of weapons statute still bars several categories of people from carrying a firearm. You cannot carry if you have been convicted of a felony, are a fugitive from justice, are subject to a court-issued order of protection, or have been adjudicated mentally incompetent or committed to a mental institution. Carrying while intoxicated and handling the firearm negligently or unlawfully is a separate offense under the same statute.1Missouri Revisor of Statutes. Missouri Code 571.030 – Unlawful Use of Weapons Most unlawful use of weapons offenses are a class D felony, punishable by up to seven years in prison.2Missouri Revisor of Statutes. Missouri Code 558.011 – Sentence of Imprisonment, Terms
Where You Still Cannot Carry
Constitutional carry does not extend into the places Missouri statute lists as off-limits. The restricted locations include:
- Police stations, sheriff’s offices, and highway patrol stations, unless the chief officer consents
- Jails, prisons, and juvenile detention facilities
- Courthouses, courtrooms, and judicial offices
- Meetings of the state legislature, legislative committees, or local governing bodies
- Within 25 feet of any polling place on election day
- Elementary, secondary, and higher education facilities, unless the governing body consents
- Child care facilities, without the manager’s consent
- The portion of any establishment licensed to serve alcohol on-site that is primarily devoted to that purpose, unless the owner or manager consents; this does not apply to restaurants seating at least 50 that get more than 51% of revenue from food
- Churches and places of worship, without consent from the minister or religious body in charge
- Publicly accessible hospitals
- Gated areas of amusement parks
- Stadiums or arenas with seating for 5,000 or more
- Riverboat casinos, without the owner’s or manager’s consent
- Airport security areas where access is controlled by inspection
- Private property posted with a sign at least 11 by 14 inches with lettering at least one inch tall, in a conspicuous place
Government entities can also prohibit concealed carry in portions of buildings they own, lease, or control.3Missouri Revisor of Statutes. Missouri Code 571.107 – Permit Does Not Authorize Concealed Firearms, Where
A vehicle exception applies at schools, colleges, amusement parks, hospitals, stadiums, airports, and posted private property: keeping a firearm inside your vehicle on the premises is not a criminal offense, as long as you don’t remove it or brandish it. Employers can still bar employees who hold a Missouri extended or lifetime permit from carrying concealed in employer-owned vehicles.
The Penalty Gap for Permitless Carriers
This is the part of Missouri law that catches people off guard. If you hold a Missouri concealed carry permit and you carry into one of the restricted locations, it is not a criminal offense. You can be asked to leave, and refusing triggers a citation scale that starts at up to $100 for a first offense, rises to $200 for a second within six months, and reaches $500 plus a three-year permit revocation for a third within a year.3Missouri Revisor of Statutes. Missouri Code 571.107 – Permit Does Not Authorize Concealed Firearms, Where
If you don’t have a permit and you’re carrying under the permitless provisions, the same act is prosecuted under the unlawful use of weapons statute. Carrying a loaded firearm into a restricted area is a class D felony. An unloaded firearm drops it to a class A misdemeanor.1Missouri Revisor of Statutes. Missouri Code 571.030 – Unlawful Use of Weapons Same conduct, radically different consequence, decided entirely by whether you got the optional permit.
Federal Restrictions Missouri Law Can’t Override
State law stops at the federal property line. Bringing a firearm into a federal facility, such as a Social Security office, VA building, or IRS office, is a federal crime punishable by up to one year in prison, or up to five if you intended to use it in a crime. Federal court facilities carry up to two years.4Office of the Law Revision Counsel. 18 USC 930 – Possession of Firearms and Dangerous Weapons in Federal Facilities
Post offices trip up a lot of Missouri carriers. Federal regulations prohibit firearms on any postal property, openly or concealed, parking lot included, no matter what state law says.5United States Postal Service. Possession of Firearms and Other Dangerous Weapons on Postal Service Property
The federal Gun-Free School Zones Act is the other big one. It prohibits possessing a firearm within 1,000 feet of any school. There is an exception for people carrying under a state-issued license, but only if the state required law enforcement verification of the license holder’s qualifications before issuing it.6Office of the Law Revision Counsel. 18 USC 922 – Unlawful Acts A Missouri concealed carry permit qualifies. Permitless carry does not. Anyone carrying without a permit near a school could face federal charges even while fully legal under state law.
National parks follow the law of the surrounding state, so Missouri carry rules apply inside places like the Ozark National Scenic Riverways. Federal law still bans firearms inside park buildings, which are marked at the entrance.7National Park Service. Laws and Policies
When You Can Use the Firearm
Missouri has both a castle doctrine and a stand-your-ground law. Deadly force is permitted when you reasonably believe it is necessary to protect yourself or another person from death, serious physical injury, or any forcible felony. It is also permitted against someone who unlawfully enters or attempts to enter your home, vehicle, or private property you own or lease.8Missouri Revisor of Statutes. Missouri Code 563.031 – Use of Force in Defense of Persons
There is no duty to retreat from any place you have a legal right to be. That reaches beyond your home and vehicle to anywhere else you’re lawfully present, which is what makes Missouri a true stand-your-ground state.
The “reasonably believes” standard controls everything. Your perception of the threat has to be one a reasonable person in the same situation would share. Getting that judgment wrong can mean criminal charges regardless of intent.
Interacting With Police While Carrying
Missouri does not require you to volunteer that you are armed during a traffic stop or other encounter with law enforcement. You must disclose it only if the officer specifically asks, and if asked, you must answer truthfully.
Should You Get the Optional Permit Anyway
Missouri still issues concealed carry permits through local sheriff’s offices, and two practical reasons make the permit worth considering even though it isn’t required:
- Carrying into a restricted location becomes a citation matter rather than a felony
- Your permit qualifies you for the federal Gun-Free School Zones Act exception, which permitless carry does not
The application requires a background check, fingerprinting, and completion of an approved firearms safety course of at least eight hours, though a one-hour NRA-certified online course paired with a practical skills session also satisfies the training requirement.9Missouri Revisor of Statutes. Missouri Code 571.111 – Certificate of Qualification for Concealed Carry Permit Fees cap at $100 for a standard five-year permit, $200 for ten years, $250 for 25 years, and $500 for a lifetime permit.10Missouri Sheriffs’ Association.

Reciprocity if You Travel
Missouri recognizes concealed carry permits from every state that issues them.11Attorney General Office of Missouri. Concealed Carry Reciprocity Many other states honor a Missouri permit in return. Without a permit, you’re bound by the carry laws of whatever state you enter, and several of Missouri’s neighbors are not permitless carry states. Crossing a state line concealed without a recognized permit can turn a lawful Missouri activity into a serious criminal offense elsewhere.
