Missouri Weapons Charge Classifications and Penalties

Unlawful Use of a Weapon (§571.030)

Missouri’s primary weapons offense statute covers a wide range of conduct. The classification depends on the specific subsection charged:¹

• Carrying a concealed firearm without lawful authority — Class E Felony, up to 4 years.¹
• Carrying a firearm while in an intoxicated condition — Class E Felony.¹
• Discharging a firearm within 100 yards of a school or church — Class E Felony.¹
• Exhibiting a weapon in an angry or threatening manner — Class E Felony.¹
• Possessing a firearm while also in possession of a controlled substance — Class E Felony.¹
• Carrying a concealed firearm into certain restricted locations (courts, polling places, government buildings) — Class A Misdemeanor.¹
• Discharging a firearm at or from a motor vehicle — Class B Felony, 5 to 15 years.¹
• Shooting at an occupied building or vehicle — Class B Felony.¹
• Discharging into an occupied dwelling — Class B Felony.¹
• Blindly discharging into a crowd — Class B Felony.¹

Under SB 888 (2026), Class E felonies require 25% of the sentence served before parole eligibility; Class B felonies require 50%.

Enhanced UUW — 15-Year Mandatory Minimum (§571.030.9)

Shooting at or from a motor vehicle at a person, building, or habitable structure, or blindly discharging into a crowd, triggers an enhanced UUW classification carrying a Class B Felony with a mandatory minimum of 15 years.¹ This is also a dangerous felony — 85% of the sentence must be served before any parole eligibility.² In a case where a defendant receives a 15-year sentence on an enhanced UUW, the mandatory minimum before parole consideration is 12 years and 9 months.

Unlawful Possession of a Firearm (§571.070)

Possession of a firearm by a convicted felon.³ Classification escalates with the defendant’s criminal history:³

Possession during the commission of another felony adds one class level to the felon-in-possession charge.³

Federal Felon-in-Possession

Federal prosecution of felon-in-possession cases under 18 U.S.C. §922(g) is common in St. Louis County when federal task forces — ATF, FBI — are involved in the arrest.⁴ The federal statute carries up to 10 years for a standard conviction. The Armed Career Criminal Act (18 U.S.C. §924(e)) adds a mandatory minimum of 15 years for defendants with three or more prior violent felony or serious drug offense convictions.⁴ Federal sentences are served at 85% with no parole — the federal equivalent of Missouri’s dangerous felony rule.

Armed Criminal Action (§571.015)

Armed Criminal Action is not a standalone weapons charge — it is an enhancement that attaches to any felony committed with a deadly weapon.⁵ ACA adds a mandatory consecutive sentence of 3 to 15 years — served after the underlying felony sentence completes — with no probation and no early release.⁵ ACA is itself a dangerous felony — 85% of that consecutive sentence must also be served before any parole consideration.² The combination of a primary felony conviction plus ACA can produce mandatory minimum prison exposure far exceeding what either charge alone would carry.

Prohibited Weapons (§571.020)

Possession, manufacture, or transfer of machine guns, short-barrel shotguns or rifles (unless registered under federal law), explosive weapons, gas guns, switchblades over three inches, brass knuckles, or defaced firearms is a Class E Felony — up to 4 years.⁶ Defacing a firearm serial number is a Class D Felony.⁷

Missouri Permitless Carry

Missouri is a permitless carry state. Under §571.101, RSMo, adults 19 and older who are legally able to possess firearms may carry concealed without a permit.⁸ Permitless carry does not apply to persons with a prior felony conviction, an adjudication of mental incompetence, or a domestic violence conviction — those persons remain fully prohibited from possessing or carrying any firearm. And permitless carry does not authorize carry in restricted locations — schools, courthouses, polling places, government buildings, and certain other locations remain off-limits regardless of permit status.

Defense Strategies for Weapons Cases in Sunset Hills

Fourth Amendment Suppression

Weapons charges most often arise from traffic stops and vehicle searches — areas where constitutional violations are common and frequently litigated. If the traffic stop lacked reasonable suspicion, if the vehicle search exceeded the scope of a lawful stop, or if a pat-down for weapons was not supported by articulable facts justifying concern for officer safety, the firearm must be suppressed. Suppression of the weapon typically results in dismissal of the weapons charge and any ACA enhancement.

Constructive Possession

When a weapon is found in a shared space — a car with multiple occupants, a home with multiple residents — the State must prove the defendant knew about the firearm and had control over it. Proximity to a weapon is not the same as possession. In cases where the weapon is not found on the defendant’s person, constructive possession is a contestable element that defense attorneys challenge through the specific facts of each case.

Challenging the ACA Enhancement

Armed Criminal Action requires that the underlying felony was committed “with” a deadly weapon — an element that is not always as clear as prosecutors assert. In cases where the weapon’s role in the offense is ambiguous, remote, or disputed, defense attorneys challenge the factual basis for the ACA enhancement. Eliminating ACA can reduce sentencing exposure by years, and in cases with mandatory minimums, eliminating ACA can be the difference between prison and probation on the primary charge.

Challenging Felon Status

For felon-in-possession charges, the State must prove the prior disqualifying conviction. Defense attorneys examine whether the prior conviction actually qualifies as a felony under Missouri law, whether the defendant’s civil rights were subsequently restored, and whether the conviction is constitutionally valid. Prior convictions obtained without the assistance of counsel or in violation of the defendant’s constitutional rights may not be used to establish felon status.

Challenging the Restricted Location

For UUW charges based on carrying into a restricted location, defense attorneys challenge whether the location actually qualified as restricted under the specific subsection charged, whether the defendant had notice of the restriction, and whether any applicable exceptions apply.
