The firearms manufacturer Kimber has recognized the importance of including less lethal means of defense within their fine defensive handgun line. For several years they have been importing and marketing a line of Swiss-made pepper projection devices that are unique among the other projectors on the market.
Almost every Oleoresin Capsicum (OC) projection device on the market sends its pepper formulation downrange via aerosol power. Aerosol is an effective system of projection. Aerosol projector canisters, made by quality manufacturers such as MSI, are reliable and can be counted on for self-defense needs. And, they are affordable. However, aerosol systems suffer from two potential deficiencies: de-pressurization during storage or carry and pressure loss during extreme heat or cold conditions. The Pepper Blaster II solves both of these issues by using a pyrotechnic power drive that operates a piston when fired.
The pyrotechnic power drive is not under constant pressure like an aerosol projection device is. Pressure to drive the OC irritant liquid from the projector is generated by the pyrotechnic explosion. It sends the pepper liquid out at a speed of 90 mph (132 fps) for a maximum distance of 13 feet, where it splats against the suspects face in a large blob, driving the OC particles deep into the pores of the skin. The charges are fired with each pull of the trigger, top barrel first.
