A stun gun is a non-lethal electrical weapon that works by charging a person's body with a low electrical current, which is then interpreted as nervous pain. It is often used for self-defense, in and out of the home. To be effective, a stun gun must be pressed against an attacker's body. Stun guns are not to be confused with the TASER, which is a trademarked brand of electrical weapon that can be used from a distance of up to 15 feet. There are specific requirements to be fullfilled for getting the legal ownership of a stun gun.
Be over the age of 18. If under 18, live in a state whose laws allow you to own a stun gun (these include Kentucky, Maine and Alabama).
Live in a state with few or no restrictions on the ownership and use of stun guns, which include the states named in Step 1, as well as Arizona, Texas, Utah and others. (Note: These days, you can get stunguns at a cheap price through various online portals.)
Familiarize yourself with the stun gun laws in your home state, if you are unwilling to relocate. Be willing to obtain a weapons permit or license, depending on local laws. Do not carry your stun gun into places where it may be prohibited, such as gaming or liquor establishments or schools.
