First Defense 1.3% MK-3 Stream OC Aerosol

First Defense MK-3

The MK-3 is a mid-size aerosol defense spray from Defense Technology's First Defense line, loaded with a 1.3% Major Capsaicinoid (MC) formula, the measure of the actual active pepper content that drives the inflammatory effect. At 1.5 ounces it sits between a pocket keychain unit and a full duty canister, which makes it a common choice for patrol officers, security staff and anyone who wants more capacity than a compact spray provides. A single can holds enough product for roughly 14 to 16 short bursts.

Features

• 1.3% Major Capsaicinoid Formula — The 1.3% rating measures the active pepper content, the part of the formula that does the work rather than the total pepper in the can.
• 1.5 oz. Net Weight — Holds more product than a compact keychain unit while staying small enough for a belt pouch or jacket pocket.
• 14 to 16 Short Bursts — Average yield per can, enough for repeated deployments or training familiarization before it runs dry.
• Flip-Top Safety Cap — The hinged top guards the actuator against accidental discharge and flips clear for a fast deploy.
• Twist-Lock Actuator — The firing button locks to prevent stray sprays when the can is carried or stored.
• Stream Delivery — Projects a directed stream that carries to the target and reduces blow-back in wind compared with a wide fog.
• Defense Technology Build — Made by a manufacturer that supplies law enforcement and corrections agencies.
• Clear Warning Label — Printed caution and usage information on the canister for safe handling and storage.

Formula And Carry

The active agent is oleoresin capsicum, the natural pepper extract that causes burning, eye closure and temporary loss of vision on contact. First Defense sprays are rated by Major Capsaicinoid content, so the 1.3% figure tells you what the formula actually delivers. The 1.5-ounce canister suits duty belt carry, a vehicle, a bag or home storage. Check your state and local regulations before purchase, since laws on defense spray size and content vary.
