A stun gun (popularly also known as a Taser, the main maker of stun guns) is a non-lethal weapon that is capable of temporarily immobilizing a person by inflicting an electrical charge.
This article describes Missouri laws regarding who may not have a stun gun, and the circumstances or situations when carrying a stun gun is illegal in the state.

In Missouri, most people may purchase, possess (openly or concealed), or use a nonlethal stun gun for self-defense without obtaining a permit.
