Summary 

• Permit required? No for most adults. Missouri allows permitless (constitutional) concealed carry for eligible people, with key location restrictions. 

• Minimum age: Generally 19 (or 18 for active-duty military/honorably discharged in certain contexts)

• Duty to inform:No general duty to proactively inform; however, permit holders must carry their permit and show it (and photo ID) upon an officer’s request. 

• Where you can carry: Broadly allowed in many public places, but restricted locations include schools, courthouses, certain government-controlled areas, secured airport areas, and posted private property (among others). 

• Visitors: Missouri recognizes concealed carry permits from every state that issues them, but you still must follow Missouri’s location rules.

Missouri is widely treated as apermitless/constitutional carry state for concealed carry by eligible adults, while still offering an optional concealed carry permit. Missouri permits are   issued locally by county (or city not within a county) sheriffs, with required background checks and training, and the law directs issuance when disqualifiers are not found—commonly described as shall-issue. 

Even with permitless carry, Missouri maintains a detailed list of restricted places where concealed carry is limited or prohibited (or allowed only with consent). These include areas such as police stations (without consent), polling places (buffer zone), detention facilities, courthouses/courtrooms, secured airport areas, schools, and certain alcohol-focused establishments, among others. 

For residents and visitors, Missouri’s reciprocity posture is broad: the Missouri Attorney General states Missouri law recognizes permits from every state that issues them. Practically, many people still obtain the Missouri permit to help with reciprocity when traveling and to simplify interactions in other states. When transporting or storing firearms in vehicles, hotels, or shared spaces, prioritizesecure storage (locked case/safe, keep it out of sight, minimize handling) and consider Faraday-protected SLNT bags for discrete, protected storage of electronics like key fobs/phones and other sensitive items—especially in hotels or shared accommodations where privacy and access control matter.
