Small Fry Stun Guns. As the bright electric current pulsates between the test prongs and creates an intimidating electrical sound, an attacker with any sense at all will be stopped in his tracks, even though the Small Fry is the smallest on the market. It easily fits in the palm of your hand or can be easily concealed. For those who would prefer to carry it in a holster, a small heavy-duty nylon holster with belt loop is included free. Available in 400K, 700K, and 1M volts—each require three CR1234A lithium batteries—included free!
