Description
The Byrna SD is the self-defense launcher that put the brand on the map, and the Kinetic Kit is the version built around solid impact rounds instead of chemical payloads. It runs on compressed CO2 and sends .68 caliber kinetic projectiles downrange at around 300 feet per second, giving you a way to stop a threat from as far as 60 feet out. For anyone who wants real standoff distance and a gun-like feel without the firearm, this is a sensible place to start.
As the successor to the original Byrna HD, the SD was reworked where it counts. The honeycomb over-molded grip gives you a secure hold even when your hands are sweaty or cold, and the ambidextrous safe/fire switch flips easily for left or right-handed use. The straight trigger and improved white dot sights make it quicker to get on target when the pressure is on. There's also a Picatinny rail under the barrel if you want to add a light or laser for low-light situations.
What Powers the Byrna SD Kinetic Kit
The SD uses Byrna's patented Pull-Pierce technology, which keeps the 8-gram CO2 cartridge sealed and unpunctured inside the grip until your very first trigger pull. That means you can store it loaded and ready without worrying about the gas slowly bleeding out. Each cartridge is good for roughly 22 shots, and the two included 5-round magazines let you reload fast.
Projectiles Packed With the SD Kinetic Kit
This kit is the kinetic-only configuration, so there are no pepper rounds in the box. You get kinetic impact rounds for defense, eco-kinetic rounds that break down in water, and inert balls for practice. Having training projectiles included means you can get real reps in before you ever need to rely on it. The whole setup lives in a protective zippered case that makes it easy to store at home or stash in a vehicle.

Frequently Asked Questions
Does the Byrna SD Kinetic Kit come with pepper rounds?
No, this is the kinetic configuration, so it ships with solid impact projectiles rather than chemical irritant rounds. You get kinetic rounds for defense, eco-kinetic rounds that dissolve in water, and inert rounds for practice. If you want pepper projectiles, those are sold separately or found in a different Byrna kit.
How far can the Byrna SD shoot?
The SD is rated to disable a threat from up to 60 feet away. Projectiles leave the launcher at around 300 feet per second, which gives you useful standoff distance in a self-defense situation. Like any launcher, accuracy improves with practice, which is why the included inert rounds come in handy.
How does the Pull-Pierce technology on the Byrna SD work?
Pull-Pierce keeps the 8-gram CO2 cartridge sealed and unpunctured inside the grip until you pull the trigger for the first time. This lets you store the launcher loaded and ready without the gas slowly leaking out over time. Once pierced, each cartridge delivers roughly 22 shots.
Can the Byrna SD Kinetic Kit accept accessories like a light?
Yes, the SD has a Picatinny rail section under the barrel for mounting a light or laser. That makes it easier to use in low-light conditions around the house. The ambidextrous safety and honeycomb grip also make it comfortable for both left and right-handed users.
