The Byrna SD is our most popular less-lethal pistol. This kit contains no chemical projectiles and is legal in all states in the US.
The Byrna SD (Self Defense) is the successor of the Byrna HD. It has been re-engineered for optimal performance. Powered by compressed air (CO2), the Byrna SD shoots .68 caliber round kinetic and/or chemical irritant projectiles that can disable a threat from up to 60-feet away. It is an incredibly powerful and non-lethal self-defense weapon.
The Byrna SD is not classified as a firearm therefore does not require a permit or background check to own. Must be 18 or older to purchase.
*This kit does not come with chemical projectiles.
*Average first 10 shots
**At room temperature
The SD features patented pull-pierce technology that stores CO2 in the launcher unpunctured until the first trigger pull. On the first trigger pull, the CO2 is punctured and a projectile is launched simultaneously. This means your SD can be stored safely with CO2 installed and activated instantly when needed.
The SD uses .68 caliber projectiles - the industry standard for maximum stopping power and accuracy. This proven caliber delivers reliable performance with both kinetic and chemical projectiles.
The Byrna SD is not classified as a firearm therefore does not require a permit or background check to own. Must be 18 or older to purchase. Legal in all 50 states and compliant with California regulations. Always check your local laws regarding less-lethal devices.
