ZAP Blast Knuckles Stun Gun – 950K Volts, 5.0 Milliamps

Most stun guns are designed to be held. The ZAP Blast Knuckles Stun Gun is designed to stay held. If you’ve ever thought about what happens to a handheld device when your palms are sweating, your hands are shaking, or someone is trying to take it from you, this product exists as a direct answer to that problem. Four fingers go through molded openings in the grip — the device becomes part of your hand rather than something you’re clutching.

Who This Stun Gun Is For

This is a practical fit for people whose daily routines put them in situations where device retention matters more than low profile. Security workers, parking lot attendants, runners who carry in hand rather than in a pack, and anyone in a role where physical confrontation is a realistic possibility. It’s also a reasonable choice for people who prefer replaceable batteries over rechargeable systems — CR123A cells can be swapped in seconds, and spares are easy to keep on hand. If discreet carry is your primary requirement, this design is visible and distinctive, and that tradeoff is worth knowing before you buy.

Is It the Right Fit for You?

Choose It If You Want

• A grip that physically locks the device to your hand through four molded finger openings
• 5.0 milliamps of output — the current that determines what the charge actually does
• Replaceable CR123A batteries with no charging downtime and a long shelf life
• A rubberized, impact-resistant build designed for rough handling

Consider Another Option If You Need

• Discreet or concealable carry — the knuckle profile is visible and distinctive
• A lighter carry option — this unit weighs 0.8 lbs with batteries installed
• A rechargeable power source rather than replaceable cells

ZAP Blast Knuckles Stun Gun Features and Benefits

• Four-Finger Knuckle Grip: Fingers pass through molded openings so the device is secured to your hand — not just held by it. Reduces the risk of losing the device during a fumble or struggle.
• 950,000 Volts: Produces a visible, audible arc that functions as a deterrent. Voltage bridges the gap to the target; the milliamp output does the work after contact.
• 5.0 Milliamp Output: Current — not voltage — is what causes involuntary muscle response. At 5.0mA, this is a high-output unit for its size class.
• Electrical Contact Orientation: When your hand is closed naturally through the grip, the contacts face outward. No need to think about device orientation under stress.
• CR123A Lithium Batteries: Two included. Known for long shelf life and reliable performance across a wide temperature range — relevant for outdoor carry in variable conditions.
• Rubberized ABS Construction: The rubberized coating adds grip texture and provides some impact resistance. ABS plastic keeps the overall weight to 0.8 lbs.
• Nylon Belt Holster Included: Carries the unit securely on a belt when not in hand. Covers the electrical contacts during storage and transit.

ZAP Blast Knuckles Stun Gun: Frequently Asked Questions

What is the milliamp output of the ZAP Blast Knuckles Stun Gun?

The ZAP Blast Knuckles Stun Gun outputs 5.0 milliamps. Milliamps represent the actual electrical current delivered on contact — they’re distinct from voltage, which creates the arc. This is one of the higher milliamp ratings available in a compact stun gun form factor.

How do you replace the batteries in the ZAP Blast Knuckles Stun Gun?

The unit runs on two CR123A lithium batteries. These are a common size available at most hardware, electronics, and outdoor retailers. No charging cable or waiting period is involved — swap the cells and the unit is ready. Keeping a spare pair on hand eliminates any downtime concern.

How big is this stun gun, and will it fit most hands?

The unit measures 4.4 inches long by 3.25 inches tall and 1.13 inches wide, weighing 0.8 lbs with batteries. The four-finger openings are sized for average adult hands. If you have very small hands, it’s worth confirming the fit before purchasing, as the grip design is fixed rather than adjustable.

Is the ZAP Blast Knuckles Stun Gun legal where I live?

Stun guns are permitted in most US states, but restrictions exist at the state, city, and venue level. Some jurisdictions require a permit; others ban them outright. Because laws change, we recommend verifying the rules in your specific location before purchasing or carrying any stun device.
