What Do Weapon Laws Cover in Kansas City, MO?
MO law covers topics like purchase, possession, and use of firearms and other deadly weapons. But that’s not all you have to worry about in MO: There are still federal laws that affect the availability and use of self-defense tools. Here’s an interesting example: MO does not require a background check for individuals to purchase a gun, but federal law requires licensed dealers to conduct one, meaning that if you want to buy a gun in MO, you should still be prepared for a background check.
In MO, the majority of people are permitted to carry a self-defense weapon, so long as:
- They do not bring it into schools, government offices, places of worship, or other restricted areas; and
- Nothing has happened to lead that person to lose their right to carry a weapon.
In MO, you’re allowed to use your gun at the range and for 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, bringing one to a polling place during an election, or firing it into a building.
One key thing to be aware of – while we’ve talked mostly about state restrictions above, MO allows for individual localities to set up their own restrictions regarding firearms and other weapons, so to make sure you’re not breaking any Kansas City laws, be sure to go through your local laws and ask a gun crime lawyer if any parts don’t make sense.

Common Weapon Crimes Defenses in Kansas City, MO
Weapon crimes will generally progress through the legal system the same way as any other criminal charges. That said, these types of cases often hinge on legal defenses like self-defense, and cases are often less about if you “did it” and more on whether the action was “justified.”
Below, we’ve listed common defense strategies Combs Waterkotte might use in your defense against Kansas City, MO, weapon crimes allegations:
- Self-Defense: Weapons are frequently used in self-defense, and related criminal charges can be argued that they do not apply. In Missouri, you have the right to defend yourself against imminent danger.
- Defense of Others: Related to self-defense, you are allowed to use force to defend another person. Some weapon charges are invalidated if you were protecting another, as they would be with self-defence.
- Castle Doctrine: MO castle doctrine states that you are allowed to use force, including weapons, to defend yourself and those in your home. While you do not have a duty to retreat, the amount and type of force you use needs to be proportionate to the threat.
- Stand Your Ground: Stand your ground is related to castle doctrine. This 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 you stole a weapon that you knew was going to be misused. You could be charged with theft, but your actions were well-intended to prevent a greater harm.
- Duress: If you did not want to commit a crime, but another person forced to do so, duress could be a valid excuse. 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 an underaged person without permission is illegal. If you honestly thought this person had parental permission, though, you could be exempt due to a lack of intent.
