A stun gun is a device that delivers an electric shock to an attacker through direct contact. The shock can cause pain, muscle spasms, and temporary paralysis, giving the user a chance to escape or call for help. Stun guns are different from tasers, which shoot metal prongs that can reach up to several yards away. Stun guns are usually smaller and cheaper than tasers, but they require close range to be effective.

Stun guns work by using batteries or capacitors to store electrical charge and release it through electrodes on the device. The amount of charge delivered is measured in microcoulombs (µC), which indicate the pain level induced by the shock. The higher the µC, the more painful the shock. According to the National Institute of Justice, 0.5 µC can cause pain, and 1.0 µC can cause intolerable pain1. Most stun guns produce at least 1.0 µC of charge.

Stun guns may also have other features, such as LED flashlights, alarms, safety switches, holsters, or anti-grab bars. These features can help increase the user’s safety and convenience. Some stun guns are designed to look like flashlights, rings, or other objects to be more discreet or less suspicious.

Stun guns are legal in most states in the USA, but some have restrictions or bans on their use or possession. It is important to check the local laws before buying or carrying a stun gun.
