In the original series, laser pistols served as the standard-issue weapon for Visitor officers and security troops; they were also frequently carried by shock troopers as a secondary weapon, in addition to their rifles. The pistol consisted of a standard grip connected to a small foregrip via a framework with the action part of the weapon divided into two parts connected by a clear tube.
The laser pistol was capable of firing bolts of adjustable strength from "stun" to "lethal" effects. It's power supply, dependent on a catalytic reaction involving cobalt, was capable of providing an unknown but considerable number of shots before depletion. The power supply may have been rechargeable.
