Discharge Information

Projection/ammo type: Solid Ammunition Firing Mechanism: Recoil Operated, A round is initially chambered by pulling back on the slide of the weapon, which carries out a mechanical action which moves a bullet out from the magazine of the weapon and into the chamber. In this same action, the weapon is cocked and ready to fire. When the trigger is pulled, the hammer of the pistol impacts the bullet's primer, thus igniting the chemical charge within the bullet casing. The ignition process releases heated gases which expand and propel the bullet down the barrel of the weapon. The resulting recoil of the bullet is harnessed through a spring mechanism which operates the pistol's action and chambers another bullet while cocking the hammer, thus preparing the pistol to be discharged again.

Additionally, excess recoil pressure is reduced through the use of recoil absorbing springs.

Full Size Arbitrator

Compact Arbitrator


With the formation of the United Outer Colonies and the United Outer Colonies Peacekeeping Forces, the weapons which were utilized by the soldiers of the Fifth Expeditionary Fleet became a sign of a time gone by. A new weapon design was needed to fit to the style and needs of the United Outer Colonies Peacekeeper Forces. Along with the Peacekeepers, the Lorath Self Defense Force was in need of a standard semi-automatic pistol design for their forces which would be able to deliver the proper firepower needed for military service. Seeing this issue, the United Manufacturing Cooperative developed the Arbitrator to serve as a proper sidearm.

Four models were produced, the Arbitrator standard, the Arbitrator compensated, the Arbitrator compact, and the Arbitrator compact compensated.
