What Is Armed Criminal Action in Missouri?
Armed criminal action is an unusual charge because it requires prosecutors to prove the commission of a felony as an element. You can only commit armed criminal action if you commit a felony while armed with a dangerous instrument or deadly weapon.
This statute allows prosecutors to seek enhanced penalties when weapons are involved in felony offenses. For example, armed carjackers may face both vehicle hijacking and armed criminal action charges, unlike unarmed offenders.
Unlike weapons enhancements in other states, Missouri’s armed criminal action law allows both the primary felony and the weapon-based charge to be contested at trial.
Charges Involving Armed Action in Missouri
Missouri law includes several weapon-related charges that can be filed alongside other crimes. These weapons offenses include:
Armed Criminal Action
This charge applies when a person commits a felony using a dangerous instrument or deadly weapon. The definitions include:
- Dangerous Instruments: Firearms, blunt weapons, knives, motor vehicles, poison
- Deadly Weapons: Firearms (loaded/unloaded), switchblades, daggers, billy clubs, blackjacks, metal knuckles
The weapon doesn’t need to be used—its presence or aid in the felony suffices. However, prosecutors must prove its relevance to the act.
Unlawful Use of Weapons
- Carrying a concealed weapon in restricted areas
- Firing guns into buildings or public spaces
- Displaying weapons threateningly
- Possessing firearms while intoxicated or using them negligently
Unlawful Possession of a Firearm
This includes possession by felons, fugitives, drug/alcohol addicts, or mentally incompetent individuals. Often charged alongside other offenses.
Possession of a Defaced Firearm
This charge applies when serial numbers on a firearm are removed or altered—often discovered during broader criminal investigations.
