Mace® Pepper Guns are great for protecting yourself in any dangerous situation.  Pepper guns have a 25 foot range compared to the traditional pepper spray canisters which generally have 12ft  spraying distance.  Pepper spray guns from Mace have the capability to test fire with water canisters that contain no pepper spray. This gives you the ability to practice using this self defense product for that emergency situation.  Testing other pepper spray usually means you have to replace them after a few test or practice shots.  With the pepper spray gun you simple replace the test water cartridge with a true pepper spray cartridge.  Testing and practicing with the pepper spray gun is very affordable and practical
