The Byrna HD is a compact non-lethal personal security device developed by Byrna Technologies Inc. (OTCQB:BYRN) for Law Enforcement, Corrections, and Private Security. We believe it to be the safest and most effective non-lethal self-defense weapon on the market today.

The Byrna HD shoots .68 caliber projectiles that are filled with a powerful chemical irritant. The projectiles are designed to burst upon impact and disperse a cloud of powerful pepper and tear gas powder.

The Byrna HD is manufactured using glass-reinforced polymers and aircraft grade aluminum. It contains more than 100 precision parts, incorporating technology from both real firearms and gas-fired launchers.

The Byrna HD is roughly the size of a compact 9mm handgun. We sell tactical holsters that have been custom designed to comfortably hold your Byrna HD as well as nylon holsters designed for compact 9mm handguns. Please see the Product Spec Sheet for more info.

We currently do not ship Byrna® products to Alaska, Hawaii, New York City (5-Boroughs and Yonkers), and Washington D.C. For more information see Shipping Restrictions.

We recommend that you always check state and local regulations relating to CO2 powered launchers and pepper self-defense products before traveling with your Byrna HD. If you are unsure you can check with the local police department. For air travel questions see below.

See Safety Data Sheets for chemical content of the Byrna HD Max projectiles and the Byrna HD Pepper projectiles for more info.

The Byrna HD is available to agencies, security companies, and governmental organizations world wide.

Our Byrna HD utilizes an 8 gram CO2 cartridge. There is no standard size among suppliers so we recommend you use Byrna® brand cartridges which may be purchased from our online store. Use of non-conforming cartridges may compromise your Byrna HD’s performance and may damage your Byrna HD, voiding your warranty.

Byrna® CO2 cartridges have a virtually indefinite shelf life. The cartridge is not pierced until the trigger is pulled so you can always keep an un-punctured CO2 cartridge in your Byrna HD to maximize its utility for self-defense. The Byrna HD incorporates puncture technology to allow it to fire on the first trigger pull. We recommend loading a new CO2 cartridge after every sustained use of the Byrna HD because once the cartridge is punctured CO2 will leak out over a 24-hour period.

A single Byrna® CO2 cartridge may fire up to 20 projectiles before a noticeable degradation in velocity, but we recommend replacing the CO2 cartridge after 2 magazines for maximum performance.
