Frequently Asked Questions

The Byrna is a compact non-lethal personal security device developed by Security Devices International Inc. (CSE:SDZ OTCQB:SDEV). We believe it to be the safest and most effective non-lethal self-defense weapon on the market today. The Byrna HD (Home Defense) shoots .68 caliber projectiles that are filled with a powerful chemical irritant. The rounds are designed to burst upon impact and disperse a cloud of powerful pepper, PAVA and tear gas powder. The Byrna 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.

No. The Byrna is powered by compressed CO2 cartridges, just like a paintball or airsoft gun.

We currently do not ship the Byrna to Alaska, California, Hawaii, Massachusetts, Minnesota, or 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 travelling with your Byrna. If you are unsure you can check with the local police department. For air travel questions see below.

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

All of our chemical irritant projectiles are very effective. We ship the Jingle Balls in place of Byrna Black to certain states where required. See Shipping Restrictions for further information. See Safety Data Sheets for chemical content of the Byrna Black and the Jingle Balls for more info.

We ship the Byrna HD to NY or MA with extra inert projectiles in place of
self-defense rounds. You can provide an alternative address for shipping self-defense rounds outside of those states. Please contact customer service at info@byrna.com if you have any questions. We hope to have local distributors of our chemical irritant projectiles in NY and MA to sell our pepper projectiles in the near future.

No. The Byrna is much more powerful than a paintball gun and will cause the paintball to rupture upon firing. This will permanently damage the Byrna. For this reason, you should not use the Byrna for paintball and using it with incompatible non-Byrna projectiles or CO2 cannisters may void your warranty.

No. The Byrna should never be pointed or fired at the head, neck or back. When it is empty the force of the gas at close range, could cause serious injury or death.

The Byrna is currently offered in South Africa outside of the U.S. Please contact and visit our dealer www.davesheer.com for more information. We are looking to expand worldwide. Please subscribe to our mailing list at the bottom of the page and check back with us regularly to find out where else the Byrna is offered. For dealers and distributors outside the U.S., please contact info@byrna.com for business inquiries.

The Byrna is available in a number of colors including Safety Orange. The Byrna is intended for self-defense in situations where police are not present to offer assistance and should not be drawn when police or armed security personnel are present. Byrnas are not equipped with an orange tip to identify them as toys because they are not toys, and we do not sell to anyone under 18. Use of the Byrna offensively or in furtherance of a crime is illegal and may subject you to civil and criminal penalties, including incarceration. You should never draw your Byrna in the presence of a police officer acting in his professional capacity or you may be shot.

We recommend you check individual airline and airport regulations as well as TSA rules (all of which are subject to change) before travelling with your Byrna. Several domestic airline carriers allow you to carry an unloaded Byrna, or similar launcher like a paintball or airsoft gun, in checked luggage. Most airlines do not permit the transport of CO2 cartridges or self-defense rounds, so we recommend ordering them to be delivered to your intended destination before travelling by air.

The Byrna HD Ready kit comes with two 8-gram Byrna CO2 cartridges. 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’s performance and may damage your Byrna, 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 to maximize its utility for self-defense. The Byrna 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 because once the cartridge is punctured CO2 will leak out over a 24-hour period.

A single Byrna CO2 cartridge should consistently fire ten .68 caliber pepper-filled, inert, or training projectiles. It may fire up to 20 projectiles, but we recommend replacing the CO2 cartridge after 2 magazines for maximum performance.

Yes. Please refer to the Operating Manual.

Dealers and distributors please contact info@byrna.com for business inquiries.

No. Byrna projectiles are manufactured for use with the Byrna HD pursuant to our
