GSI-21D
From Wookieepedia, the Star Wars wiki.
The GSI-21D was a disruptor pistol used by the Sith army's officers and elites during the end of the New Sith Wars, and was not issued to common troops. It was manufactured by Galactic Solutions Industries, and was illegal under most Galactic Republic Sectors. Its best range was 20 meters, and its power pack held a dozen rounds. The 21D was capable of vaporizing armor, flesh and droid metals with equal efficiency.
