The First Defense OC/CS MK-9 Stream Aerosol from Defense Technology (part no. 1030661) is a duty-belt OC/CS pepper spray with a grey-banded canister and a stream delivery method. The 13.4 oz MK-9 features an easy-to-use trigger handle and delivers 14 short bursts at an effective range of 18-20 ft. It is intended for use in crowd management. The OC/CS formulation uses a stream delivery method for greater standoff and is not EDW safe. It is far larger than the belt-carried MK-2, MK-3 and MK-4 canisters.
