Top UFC Fighter Cory Sandhagen Tests the Real-World Impact of the Byrna SD
After a full day of training, the conversation shifted from mechanics to responsibility. While non-lethal self-defense tools are often evaluated through demonstrations and range time, one critical question stood out: What does it actually feel like on the receiving end?
That question led to a firsthand test.
To better understand the force and deterrent effect of a non-lethal launcher, Cory Sandhagen, a top UFC fighter, agreed to take a direct hit from the Byrna SD. The purpose was simple but important—anyone considering the use of a defensive tool should understand not only how it functions, but the real impact it delivers to an aggressor.
The Byrna SD, one of the most popular and widely used non-lethal launchers available, was selected for the demonstration. With no hesitation, Sandhagen stepped into position.
On the count, the launcher was fired.
The response was immediate. The impact was sharp, painful, and impossible to ignore. Even with humor afterward, the takeaway was clear: the Byrna SD delivers significant stopping power despite being non-lethal.
When asked how many hits it would take to disengage, the answer came instantly—one. Beyond the physical pain, the psychological effect was just as powerful. Simply standing with the launcher aimed for several seconds was enough to force hesitation and create distance. Combined with the impact itself, the deterrent effect was undeniable.
The conclusion was straightforward. A single shot was enough to stop the encounter and trigger an immediate retreat. Additional shots would be unnecessary.
The demonstration reinforced a critical point: non-lethal does not mean ineffective. Understanding both the physical and psychological effects of a self-defense tool is essential, and firsthand experience leaves little doubt about its real-world effectiveness.
