This compact blaster was crafted from hadrium alloy, and featured a ridged handgrip with guardless trigger. The muzzle featured a brake to absorb the emitter flash, and both the igniter pin and blaster gas loading port were located on the grip beneath the barrel. The pistol was noted for its impressive stopping power, despite its small size, and, though expensive, became popular amongst assassins for its subtlety.
Zam Wesell wielded a KYD-21 as her primary weapon, sometimes used in conjunction with a projectile rifle which fellow bounty hunter Jango Fett insisted she use. The clone commando Darman Skirata wielded a KYD-21 during the Clone Wars, and Ghez Hokan was known to carry a custom version.
