Missouri Gun Control Laws at a Glance

While the Second Amendment to the U.S. Constitution guarantees the right to bear arms (which has been interpreted very broadly by the Supreme Court), states have some freedom to regulate the sale and ownership of guns. Missouri gun control laws are fairly limited, compared to other states, lacking waiting periods or the requirement of background checks when guns are purchased from unlicensed dealers.

What Guns are Considered Illegal in Missouri?

Missouri prohibits the sale or possession of certain firearms that also are banned under federal law, including:

Explosive weapons
Gas guns
Exploding bullets/projectiles
Machine guns
Short-barreled rifle or shotgun ("sawed-off")

Additionally, state law prohibits the use or sale of silencers. Exceptions include the use or possession of an otherwise banned weapon displayed in a museum or used in an official capacity (such as law enforcement or military use).

Who May Not Own Weapons in Missouri?

Those who are convicted of dangerous felonies; fugitives from justice; habitually intoxicated; mentally incompetent; under 21; dishonorably discharged from the military; Missouri residents for less than six months; or not U.S. citizens may not own firearms in the state.

The basics of Missouri's gun control laws are summarized below. See FindLaw's Gun Laws article for a concise overview of the topic.
