It is only legal to buy a can of safety spray that is small enough to fit inside a standard pocket.

The Byrna Launcher is an incredibly powerful and effective non-lethal self-defense weapon that can be taken virtually anywhere. Powered by compressed air (CO2), the Byrna Launcher shoots .68 caliber round kinetic and chemical irritant projectiles that can disable a threat from up to 60-feet away.
The Byrna Pepper and Max projectiles, which can be used in the Byrna SD launcher, have an effective range of up to 60 feet with an average projectile speed of 300 feet per second. With both kits you can incapacitate a threat without hitting a specific target.
For all intent and purpose, the Byrna is a longer range security device. It is designed to deliver a pepper ball (technically a “Chemical Irritant”) to a distance of about 15 to 20 steps with enough force to break the ball with the sole intent of changing a person's mind about doing what they have set out to do.
The accuracy is good, and the effective range is listed as thirty yards, which is more than enough. Overall, I would definitely recommend the Byrna HD for those looking for a non lethal option for home or self defense.
Pronounced bur-nah, the Byrna HD is the best-in-class CO2 powered hand held personal security device. The Byrna HD fires 68 caliber chemical irritant projectiles filled with a highly potent cocktail of OC (pepper spray), CS (tear gas), and PAVA (synthetic pepper spray).
Each cartridge (new) will be good for 15-20 rounds (4 mags in a 5 round magazine) at full speed.
The standard shelf life of a PepperBall projectile is two years. After that time a projectile may still work but the potency will diminish over time.
