The pistol is a semi-automatic weapon with medium range, and a massive cool down, meaning it can fire multiple shots before it overheats. However, while its damage is fairly good, it will require one more shot than the DT-12 to kill an enemy soldier.
The Hutt Contract needed to unlock the weapon (Bounty Hunter I) requires achieving 3 Blaster Pistol Streaks (Get 7 kills with a Blaster Pistol in a round and it will count as a streak) and getting 15 kills with the Scout Pistol.
This weapon made a small appearance in Return of the Jedi when Luke grabbed this blaster from a guard with his force powers. It also appears in the Clone Wars TV show, used by Turk Falso in season one.
