The JPX Protector 2-shot cartridge holds two tubes filled with the active solution or with a marker available for training purposes. The filling volume is 10 ml (0.28 fl.oz) per cartridge. The cartridges are powered by a 9mm blank cartridge. Each 2-shot cartridge can be used twice and is replaced as a singular unit. Depending on their payload the 2-shot cartridges are marked with a specific label. The patented cartridge design provides a unique self-clean mechanism cleaning from residues, so that after you fire one shot, you aren’t exposed to the residues from the fired barrel. The content of active Capsaicinoides in the Piexon OC solution is between 2.0 and 2.5%, measured with the HPLC method. Capsaicin content is 1.5%
