The First Defense inert version of the popular Def-Tec MK-9 Stream is ideal for law enforcement training. Its realistic weight, operation method and spray pattern make it perfect for pepper spray training including presentation, application and control techniques. The inert formula does not contain any capsaicinoids, ensuring safe use. The green colored canister distinguishes the MK-9 as a training aid, preventing any confusion. Independent laboratory testing ensures its consistent quality and strength.
