When it comes to personal protection, I don't believe there's one tool that's right for every person or every situation. A gun might be the best choice when you're facing an imminent threat of death or serious bodily harm, but not every dangerous encounter rises to that level. Pepper spray, knives, and handheld electronic devices can be effective, but their limited range has some obvious drawbacks.
That's the space where Byrna's less-lethal launchers can make a lot of sense.
Take the Byrna SD, the company's flagship launcher. It's roughly the size of a compact handgun, but instead of firing bullets, it uses compressed CO2 to launch .68-caliber projectiles. Depending on what you load into it, those can be solid kinetic rounds or projectiles containing chemical irritants. Byrna rates the SD at 280 feet per second, with up to 22 shots available from a single CO2 cylinder.
One feature I particularly like is Byrna's first-shot pull-pierce system. The CO2 cylinder remains unpunctured until the first pull of the trigger, instead of slowly losing pressure while the launcher sits unused. That allows you to have your Byrna on hand ready to go in case it’s necessary, without having to fumble around when seconds count.
For those who want something even smaller, there's the Byrna CL, introduced in 2025 with everyday carry specifically in mind. It uses .61-caliber projectiles and is designed around concealability and simplified operation.
At the other end of the spectrum are products like the Byrna LE, with greater velocity and performance, as well as larger platforms such as the Mission 4.
The launchers are only half the equation, though. What they launch is equally important.
Byrna's Kinetic Projectiles rely on blunt-force impact. Its Pepper Projectiles break on impact and disperse an OC/PAVA irritant, while Max Projectiles add CS tear gas to the mixture. There are also inert Pro Training Projectiles that mimic the behavior of the chemical rounds without exposing everyone to pepper or tear gas.
That last option is a bigger deal than it might sound.
Whatever you rely on for personal protection, you need to know how to use it. Under stress, we don’t magically become John Wick. Fine motor skills deteriorate, people miss, and equipment that hasn't been practiced with suddenly becomes a lot more complicated.
Being able to practice with the same launcher you're relying on for defense is a major plus.
None of this makes a Byrna (or any other self-defense tool) a magic wand. Less-lethal does not mean harmless, and no defensive tool guarantees that an attacker will immediately stop what they're doing. Chemical irritants don't affect everyone identically, either. And yes, you also need to understand the laws governing possession and use where you live.
Look, I’m not giving up my guns and swapping them out for Byrnas, but I do appreciate having a less lethal option on hand.
There are plenty of situations where you'd desperately want something more effective than a stern voice and some harsh language, but where deadly force might not be warranted. There are also people who aren't comfortable owning a firearm but still want the ability to protect themselves from a violent encounter.
A Byrna gives them distance, multiple shots, the option of kinetic or chemical projectiles, and something that’s invaluable in an emergency: time. Time to get away, to get behind a locked door, or even for police to arrive. That, in turn, can give you more precious moments with the ones you love.
Self-defense isn't about having the most powerful tool available. It's about having the right tool when you need it… and knowing how to use it.
A Byrna can fill that role, and with a wide variety of products to choose from, chances are there’s one that’s right for you.
