The First Defense MK-3 Police Pepper Spray is the perfect balance between size and efficacy for aerosol deployed chemical agents. There is enough solution in each MK-3 to ensure 10-12 short bursts of irritant can be deployed to subdue a violent attacker using non-lethal means. With the spring loaded flip top blocking accidental discharges the MK-3 can be carried in a pouch on your belt or in your pocket without fear of accidental deployment. Once you need to bring the MK-3 into service it is as simple as flipping up the top and pressing the activator button.
