Byrna SD Launcher

The Byrna SD (Self-Defense) Launcher is Byrna's flagship personal security device — the launcher that started the non-lethal revolution. Compact, lightweight, and easy to use, the Byrna SD is designed for everyday civilians who want an effective, legal self-defense option that doesn't require a firearms license or background check in most US states.

Effective Non-Lethal Self-Defense

The Byrna SD fires .68 caliber kinetic and chemical irritant projectiles at up to 340 fps, delivering a powerful, painful impact that stops threats without causing permanent injury or death. Pepper/OC chemical irritant rounds deploy a cloud of oleoresin capsicum on impact, causing immediate eye closure, respiratory distress, and disorientation. Kinetic rounds deliver blunt impact force without chemical agents.

Compact and Easy to Carry

The Byrna SD's compact pistol-format design fits comfortably in a holster, purse, backpack, or vehicle console. It weighs just over a pound loaded, making it practical for everyday carry without the weight and bulk of a firearm. The ergonomic grip and intuitive controls make it easy to operate under stress, even for users with no prior firearms training.

CO2 Powered

A single 12g CO2 cartridge powers the Byrna SD, providing consistent velocity and reliable performance. CO2 cartridges are inexpensive and widely available, making the SD economical to train with. The cartridge changes quickly and tool-free, keeping the launcher ready for immediate use.

5-Round Magazine

The Byrna SD feeds from a 5-round magazine that loads quickly and drops free for fast reloads. Five rounds of pepper or kinetic projectiles is more than sufficient for most self-defense scenarios, and spare magazines can be carried for extended situations.

Legal in Most US States

No background check, no license, no registration required in most US states. The Byrna SD is an accessible, effective self-defense option for anyone who wants meaningful protection without the legal and ethical complexities of lethal force.
