FAQ

WHAT IS A BYRNA LAUNCHER?

A Byrna is a compact non-lethal personal self-defense device. We believe these launchers to be the safest, most effective and most reliable non-lethal self defense weapons on the market today.

HOW DOES A BYRNA WORK?

The Byrna Launcher is not considered a firearm, however, it is not a toy! It is a highly effective less-lethal weapon. While it is legal to carry in all 50 states*, it should only be used for lawful purposes, including self-defense. Like any other weapon, be it a hammer, knife or baseball bat, the Byrna should never be brandished or used in a threatening manner, except as necessary in the defense of oneself or others.

IS A BYRNA CONSIDERED A FIREARM?

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

HOW BIG IS THE BYRNA? WILL IT FIT IN A HOLSTER?

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.

WHY DOESN'T THE BYRNA HAVE AN ORANGE TIP?

Byrnas not equipped with an orange tip because they are not toys. The orange tip is designed to convey that “gun” is not an actual weapon. The Byrna is a weapon, albeit a less-lethal weapon. Accordingly, we do not sell to anyone under 18.
