Pepper Shotã¢ is a 10% pepper spray rated at 2 million scoville heat units and made with a very fine grain that is more effective than the coarser grains of most other pepper sprays. In addition to causing an attacker pain, Pepper Shot swells the mucous membranes, which makes breathing difficult, and swells the veins in the eyes, causing the eyes to close. These effects last 20-30 minutes and cause no permanent damage. All sprays have locking actuators for extra safety. This is one of our most popular pepper sprays. It fits on the visor of your vehicle, giving you pepper protection where you need it the most.
