The Black Jack 21M is built for clear, confident operation. Grip the body and Squeeze-N-Stun engages—no tiny toggles, no guessing which mode you’re in when adrenaline spikes. That same design philosophy shows up everywhere on this model: the flashlight can stay on while you stun, so you don’t give up situational awareness just to access power.

Streetwise stacks the deck with a Triple Defense System: start by lighting the scene; if the situation persists, unleash the 120 dB alarm to draw attention; if escalation is unavoidable, deploy the stun. At the business end, Triple Stun Protection arcs across three contact points, creating a loud, visible crackle that often ends a confrontation before contact.

Control and retention matter just as much as power. The disable-pin lanyard prevents an attacker from turning your own tool against you—if it’s yanked away, the pin pulls free and the unit won’t fire. A positive safety switch and ergonomic grip further reduce mistakes and help the device stay planted in the hand.

Daily use stays simple: the slide-out wall plug makes charging a non-event (no cords to remember), and the included belt-loop holster gives you reliable placement on walks, commutes, or late shifts. The Black Jack carries a lifetime warranty—a confident sign that the brand expects it to be part of your routine for years.
