For well over 25 years, Streetwise Security Products has been the world's leading brand of innovative self-defense and security products.

The innovation continues with the brand new Black Jack 21M Stun Gun with Alarm. This revolutionary new product is likely to make the old, standard models obsolete.

This stun gun is the result of feedback from people regarding the features they wanted in a self-defense product. Not only does this new model feature a loud alarm, but the new Squeeze -N-Stun Technology saves you valuable time in not having to fumble around for the right buttons to push in a panic situation.

Stun Guns are an effective defensive weapon, especially for women. Simply touching an attacker with a stun gun for 3 to 5 seconds delivers a high-voltage shock, causing loss of balance and muscle control, disorientation and confusion – enough to stop any further aggressive activity – giving you the time you need to escape the threat.

Full recovery takes about five to ten minutes; there is no permanent harm when used properly.

Send the right message to any would-be attacker: You Will Not Be A Victim!


Recently Improved: Our customers loved the first design of this model but some did not like that the fact that the alarm sounded as soon as the safety was turned off. We have redesigned this feature and now there is a separate switch position for the alarm.

Stun Now Works with Light On: This is the first model we are aware of to incorporate this potentially life saving feature. If you are using the flashlight at night and someone sneaks up and grabs you from behind you simply squeeze the unit to activate the stun gun. In all other models you have to waste valuable time moving the switch from the light to stun position.

Squeeze and Stun Technology: When it comes to protecting yourself, saving seconds can save your life! Even in a panic situation, the stun gun can be activated quickly and easily by simply squeezing it. This new technology saves you valuable time by not having to fumble around for the right button to push and your tight grip around the unit prevents it from being knocked out of your hand.

Ergonomic Design: Unlike many other models that feel awkward and bulky, this ergonomic design provides you with a comfortable, firm grip that feels natural in your hand. This can give you greater confidence in your ability to defend yourself even under stressful situations.

Loud Alarm: Self-defense experts say that a loud alarm is one of the best deterrents to attack. In the past a personal alarm needed to be purchased and carried separately. But this feature is built in to this stun gun. At the first sign of danger the alarm can be activated to summon help and scare off a potential attacker.

Triple Stun Protection: The electrical charge jumps between three points on the top of the stun gun creating a loud, bright electrical burst.

Three-in-One Defense System: Criminals love to lurk in the dark. If you illuminate the area with the bright flashlight, they will often scatter. If the threat still exists, you can sound the 120 dB alarm to summon help and scare off your attacker. If the light and alarm are not enough to stop them, the stun gun can be used.

Two Safety Features: In order to prevent the stun gun from accidentally going off and to keep your curious “little ones” safe, the pin can be kept in a separate compartment inside your purse when storing the stun gun. The stun gun will not work until the disable pin is inserted into the bottom of the unit and the safety is turned off.

Disable Pin: Prevents an attacker from taking the stun gun away and using it against you. A lanyard worn around your wrist attaches to a disable pin on the bottom of the unit. If the stun gun is taken from you, the pin will be pulled out, preventing it from working.

Built-In Charger: The slide-out plug on this unit allows for easy charging. There are no cords to keep up with; simply plug into a standard wall outlet. Complete charging instructions are included.

Holster Included: A stylish, durable holster with belt loop is included for easy carrying.

Lifetime Warranty: The BlackJack 21M is made by Streetwise Security Products – the leader in the personal protection industry and comes with a lifetime warranty. See the enclosed instruction manual for complete details.
