Why this safe
The Byrna SD is the original and most popular launcher, the one that established the Byrna brand as a serious less-lethal product. .68 caliber gives the kinetic impact a larger profile than the .61 CL. 22 shots per 8g CO2 means the user has a meaningful reload window. The ambidextrous safe/fire switch and straight trigger with a 6-8 lb pull make the SD equally accessible for right-handed and left-handed users.
Why it matters
The SD's .68 caliber is also the ammo size for Byrna's Max projectiles, the OC + CS combination round. Larger caliber means higher chemical payload and better dispersion on impact. For home defense and personal protection scenarios where the user needs to stop an attacker, that combination is meaningful. 60 feet is a real engagement range, not a marketing number.
Who it's for
First-time Byrna buyers who want the flagship model. Home protection users who want a less-lethal option for the bedroom or office. People who want the highest available chemical payload in a Byrna round. Anyone who trains ambidextrously and needs a safe/fire switch accessible from either side.
