The Dragon series from Phazzer has several advantages that make it a frequent choice for law enforcement. A rechargeable lithium-ion battery for “always charged” capacity, an intuitive design that makes operation second nature, a laser sight for increased accuracy and the ability to be used as a traditional stun gun after deployment or unloading the single-use cartridge are just a few. It also comes fully charged so that it may be used upon receipt with no registration or activation required, which is in accordance with U.S. Department of Justice, Bureau of Alcohol, Tobacco, Firearms and Explosives law. MSRP $329.99.
