Switzerland-based Piexon has developed the JPX Pepper Gun for both law enforcement and civilian use. The JPX is different in that it is mechanical in nature, very much like a hand gun, and uses a patented propulsion system that can fire liquid OC at 405 mph up to 23 feet. Each cartridge offers two separate shots and can be snapped on the receiver in seconds. The OC is very concentrated at 4 million scoville units compared to the standard police spray of 2 million scoville units. The four-shot JPX4 is scheduled to be available in the United States soon.
