Stun guns are one of the popular non-lethal self-defense weapons available on the market. These electronic devices deliver high voltage electric charges, which temporarily disable the attacker for about 10 to 15 minutes. In a world with increasing incidences of crime, more and more people buy stun guns as a defensive measure. People buy stun guns instead of real guns because they have the comforting feeling that they do not carry a deadly weapon, but at the same time, their protection is ensured.

Some states, counties, and cities in the nation restrict the usage and ownership of these devices. Hawaii, Massachusetts, Michigan, New Jersey, New York, Rhode Island, and Wisconsin are among the states that do not allow people to buy and carry stun guns. Annapolis, Baltimore, and Baltimore County in Maryland, Dension /Crawford County in Iowa, Chicago in Illinois, District of Columbia, and Philadelphia are cities and counties that have regulated personal stun guns, even though they are legal in other parts of the states. The laws in these places require people to go through the same kind of checks to buy a non-lethal stun gun as they do for lethal firearms. So before deciding to buy stun guns, it is necessary to check the state, local, and federal laws regarding the possession of the devices. One can also contact the local police department for details.
