Designed for law enforcement, corrections, and military personnel, this vapor formula offers a rapid and effective way to gain control of threatening subjects.

The MK-9S (Model 43890) uses an extremely potent formulation designed to stay in emulsion to ensure delivery of the same levels of agent to the target consistently. Unlike other brands, the active ingredient in the MK-9S OC Vapor will not separate and remains in the canister.

The MK- 9S delivers 8 – 10 short bursts and has an effective range of over 15 feet, with a total weight of 12.7 ounces. The vapor primarily inflames the mucous membranes, upper respiratory tract, and exposed skin resulting in shortness of breath along with pain, discomfort and a burning sensation. Once the subject is removed from the contaminated area to fresh air, the respiratory effects are resolved within minutes.

The MK-9S with wand (Model 43896) is ideal for indoor tactical use and, when discharged into enclosed spaces, will help dislodge and detect hiding non-compliant subjects. Uses for the MK- 9S also include penetration under doors, food ports and window gaskets. Available for order now, MSRP is as follows:


  • MK-9S OC Vapor .7% w/ Wand Adapter 43890 $49.00
  • MK-9S OC Vapor .7% 43896 $45.00
