The ST-1 Blaster Pistol is a Imperial weapon, that it is used by some of the Imperial Units. It is also a great weapon and asset to have. However this weapon isn't anywhere mentioned in Star Wars history, though it look remarkably alike to those of the Scout trooper blaster pistol seen in Episode six. If it is indeed the same weapon, the finger are to be held by two fingers. To fire the weapon, one must press into the pressure sensitive plate that replaces the trigger, due to scout trooper's glove.
