The Smith & Wesson SWP-1403 Pepper Shield Keychain Pepper Spray is one of the most effective methods of personal protection and with one short blast, it can incapacitate one or more attackers for 30-minutes. Simply point the unit at an attacker and depress the actuator button to cause severe irritation to the eyes, throat and skin. The active ingredient oleoresin capsicum (0.15-percent) is derived from hot peppers and affects the eyes, nose and entire respiratory system to restrict attackers from further aggression. This method of self defense is recommended and used by law enforcement and offers a fast acting way to immobilize attackers. This unit has a 10-foot range (varies with wind conditions) and includes 0.5-ounces of pepper spray, a black plastic case and key chain quick release for access to your Pepper Shield at a moments notice.
