How Do Weapon Laws Work in Kansas City, Missouri?

Missouri law covers topics like purchase, possession, and use of guns and other weapons. State laws overlap with federal laws to create a web of regulations. For example, Missouri does not require a background check for individuals to purchase a gun, but federally-licensed dealers are required to conduct one.

In Missouri, most citizens are permitted to carry a firearm, so long as:

  1. They do not carry it into certain locations, including schools, government buildings, airports, churches, etc., and
  2. They have not lost their right to carry a firearm.

Firearms usage in the state allows for standard target shooting and self-defense, but certain actions are illegal. These actions mostly consist of those that would threaten others’ safety, such as using the gun in a threatening manner, firing one while intoxicated, or using one while committing another crime.

One quick note – while we’ve talked mostly about state laws above, Missouri allows for individual municipalities to set up their own restrictions on weapon possession, so to make sure you’re following Kansas City laws, be sure to check your local statutes and consult with a gun crime lawyer if you’re unclear on any regulations.

Common Weapon Crimes Charges in Missouri

While there are a variety of weapons charges you can face in Kansas City, Missouri, here are some of the most common types of cases that we’ve helped defend at Combs Waterkotte:

Non-Firearm Weapon Laws in Missouri

It’s also important in Missouri to be aware of laws for non-firearm self-defense items. Common self-defense items, including pepper spray and stun guns, are legal to possess in Missouri without any permits.

Knives, blackjacks, and batons are special in that they are treated as dangerous weapons. Because of this, even though they are not firearms, they generally have the same restrictions, and also cannot be carried into restricted areas.

However, as mentioned above with firearms, different localities can have different restrictions, so don’t be afraid to ask a Kansas City weapons law expert if you’re unsure about a particular self-defense item.

Missouri Weapon Crimes Penalties:

The penalties for alleged weapon crimes in Missouri are steep. Here’s what you could be facing if you don’t hire a weapon crimes defense attorney early:

Alleged Crime Violation Sentence
Defacing a Firearm Class A Misdemeanor Up to 1 year in jail and a $2,000 fine
Unlawful Transfer of Weapons Up to a Class E Felony Up to 4 years in prison
Fraudulent Firearm Purchase Class E Felony Up to 4 years in prison
Unlawful Discharge of a Firearm Up to a Class D Felony Up to 7 years in prison
Unlawful Possession of a Firearm Up to a Class B Felony 10-20 years in prison
Unlawful Use of a Weapon Up to a Class A Felony Up to 10-30 years or life imprisonment
Armed Criminal Action Unclassified Felony Adds at least 3 years onto a prison sentence, which cannot be avoided with probation or parole

When you look at the potential fallout of a conviction, why would you not hire a Kansas City weapon crimes defense lawyer?

When you’re hiring a Kansas City, Missouri, weapon crimes defense attorney, it’s not enough to hire just anyone – you need someone who will fight relentlessly for your rights, and won’t rest until you get the justice you deserve.

  • Reputation: You want to work with someone who is known for success. Combs Waterkotte has a stellar reputation amongst clients, peers, and professional organizations.
  • Resources: Solo lawyers will try their best, but for serious weapon crimes charges, you want a strong team of skillful individuals at your back.

Common Weapon Crimes Defenses in Kansas City, Missouri

Weapon crimes can be defended in similar ways to many other criminal allegations. However, they are more likely to involve tactics like claiming self-defense, and defenses can focus less on whether you “did it” and more on whether the action was “justified.”

Here are some of the defense strategies our team might use in your case against Kansas City, Missouri, weapon crimes charges:

  • Self-Defense: Weapons are frequently used in self-defense, and related criminal accusations can be invalidated in many cases. In Missouri, you are allowed to take actions to protect yourself from imminent danger.
  • Defense of Others: Similar to self-defense, you can take action to protect another person from harm. Some weapon charges can be related to this in the same way that they can be related to self-defense.
  • Castle Doctrine: Missouri castle doctrine dictates that you are permitted to use force, including weapons, to protect yourself and those in your home. While you do not have a duty to retreat, the force used needs to be proportionate to the threat.
  • Stand Your Ground: An extension of the castle doctrine, the stand your ground law in Missouri dictates that you have no requirement to retreat before using force (including weapons) to defend yourself, as long as you were permitted to be in that location in the first place.
  • Necessity: If you find yourself in a tight spot, where something bad is going to happen, and the only way you can stop it is by breaking a law, you can claim necessity. Perhaps in an effort to scare off someone threatening you, you fired a warning shot. You could be accused of an unlawful discharge, but you needed to do so to prevent a greater harm.
  • Duress: If you did not want to commit a crime, but you were forced to do so, you can claim duress as a defense. An example of this might be if you removed the serial numbers of a firearm, defacing it, but only did so because someone threatened you.
  • Lack of Intent: Some weapon crimes require intent to be guilty. For example, giving a blackjack to a person under the age of 18 is illegal without their parents’ permission. However, if you honestly thought the person was older, you would not have had intent.

Kansas City, Missouri, Weapon Crimes Defense FAQs

What self-defense weapons are legal in Missouri?

Common self-defense tools that are legal to use in Missouri include firearms, stun guns, tasers, pepper spray, and batons, although some face special restrictions.

Additionally, it’s important to note that when acting in self-defense, the response must use a level of force proportionate to the threat.

What is the penalty for armed criminal action in Missouri?

Armed criminal action involves the use of a deadly weapon while committing another felony. The prison sentence it adds is in addition to the penalties for the other felony, and depends on whether the person was previously convicted of armed criminal action:

First offense: Adds 3-15 years (or 5-15 years if the gun was illegally possessed)

Second offense: Adds 5-30 years (or 15+ years if the gun was illegally possessed)

Third+ offense: Addes 10+ years (or 15+ years if the gun was illegally possessed)

Additionally, any penalties added because of armed criminal action are ineligible for parole or probation.

What is the Castle Doctrine in Missouri?

Missouri castle doctrine is a part of §563.031, RSMo 2016, which allows individuals to defend their dwelling, residence, or vehicle from aggressors, without needing to retreat.

However, this does not mean you can shoot someone just for trespassing on your property. Deadly force is only permitted when facing “the use or imminent use of unlawful force.”

What counts as self-defense in Kansas City, Missouri?

Missouri’s self-defense law allows one to use force to defend oneself from a threat, provided that the defensive force is proportional to the threatening force.

Self-defense is legal when it is used to protect oneself (or others) from attack, when they are unable or not required to retreat, or to defend their home/vehicle.

As a stand your ground state, in Missouri, citizens do not have a duty to retreat from a threatening situation, as long as they have a right to be in that location.

How do I defend against weapons charges in Kansas City?

Common defense strategies in weapons cases include self-defense, the defense of others, castle doctrine, and stand your ground.

How can you lose your right to own a gun in Kansas City?

People in Missouri can lose their Second Amendment rights in a few ways:

  1. If they receive a felony conviction
  2. If they are a fugitive
  3. If they are regularly drunk or drugged
  4. If they are deemed mentally incompetent
  5. If, in accordance with federal laws, they have been convicted of misdemeanor domestic violence charges.
Can police search your car for weapons without a warrant?

While you are protected from unreasonable searches and seizures, police can still search your car for weapons if they have probable cause, if you consent, if they are checking for their safety after an arrest, or if your car is impounded.
