TSA Firearms laws in Missouri

This record describes TSA's federal passenger baggage requirements. It does not verify firearm possession, carry permissions or other state, local or international laws at any point of the trip. Separate rules apply to law-enforcement officers flying armed. A firearm must be unloaded and secured in a locked, hard-sided container that completely prevents access, and transported as checked baggage only. A locked case that can easily be opened is not permitted; the original purchase case may be insufficient. Declare each firearm whenever you present it for checked-baggage transport at the airline ticket counter, and declare ammunition to the airline. Check airline limitations and fees. Only the passenger should retain the key or combination unless TSA requests it to open the container for a compliance inspection; TSA-recognized locks are permitted. Firearms, firearm parts such as magazines, clips, bolts and firing pins, and replica firearms including toy replicas are prohibited in carry-on baggage. Rifle scopes are allowed in carry-on and checked baggage. Ammunition is prohibited in carry-on baggage. Bringing an unloaded firearm with accessible ammunition to the security checkpoint carries the same TSA civil-penalty treatment as bringing a loaded firearm; this description does not establish a penalty amount. Small-arms ammunition up to .75 caliber and shotgun shells of any gauge must be packed in a fiber, wood, plastic or metal box specifically designed for ammunition and declared to the airline. Properly packed ammunition may share the firearm's locked hard-sided case. Magazines or clips may be used to pack ammunition only if they completely enclose it. Loaded or empty magazines and clips must be securely boxed or contained in a hard-sided locked case. Check airline ammunition quantity limits. These baggage rules do not authorize otherwise unlawful possession or travel. Check applicable laws in every jurisdiction involved, and consult U.S. Customs and Border Protection requirements before international travel with a firearm.
