Do I Need a Permit to Buy a Gun in Missouri?
Woody's answers are based on published federal and state law. Not legal advice. Consult a licensed attorney for your specific situation.
No permit is required to purchase firearms in Missouri. You only need to pass a federal background check and meet standard eligibility requirements for most gun purchases.
What This Means for You
Missouri operates as a constitutional carry state with relatively permissive gun purchase laws. This means you can walk into a gun store, pass the federal background check, and walk out with your firearm the same day in most cases. The lack of state-level permits streamlines the buying process significantly compared to more restrictive states.
The Detail
Missouri eliminated its permit-to-purchase requirement in 2007, making it one of the more gun-friendly states in terms of acquisition laws. When you buy from a licensed dealer, you'll still go through the federal Form 4473 and NICS background check process, but there's no additional state permit or waiting period required. Private sales between Missouri residents are also legal without permits or background checks, though federal prohibited person restrictions still apply.
The state does issue concealed carry permits for those who want them, primarily for reciprocity with other states, but these aren't required for purchase or even carry within Missouri since constitutional carry took effect. You still need to meet federal eligibility requirements, meaning no felony convictions, domestic violence restraining orders, or other disqualifying factors.
For NFA items like suppressors, short-barreled rifles, or machine guns, you'll follow the standard federal NFA process with ATF Form 4 transfers and tax stamps. Missouri state law doesn't add additional restrictions beyond federal requirements for most NFA items. However, specific local ordinances may vary, so you should verify any municipal restrictions in your area.
Age restrictions follow federal guidelines with 18 for long guns and 21 for handguns from licensed dealers. Private sales can be more flexible on age requirements, but federal restrictions on handgun possession by those under 21 still apply in most circumstances.
Build Impact
This permissive legal environment makes Missouri attractive for firearms enthusiasts and builders. You can acquire parts, complete firearms, and even NFA items without navigating complex state-level permit systems, though you should always verify current laws with official state resources before making purchases.
