The TOR Fusion is a rail-mounted white light and aiming laser combination specifically designed for pistols. It is small enough to fit inside the majority of all commercially produced holsters on the market. The TOR Fusion is based on mil spec engineering, resulting in a device that is tested and proven to operate in extreme climates and conditions including ultra-cold weather. Built with a Type III hard-anodized machined aluminum housing, framed by a rail mount and illuminator bezel, ambient sealed, dustproof and is splash-proof to IP54. The TOR Fusion features left and right fire buttons for ambidextrous use; cool white LED and total internal reflector produces a uniform circular illumination spot plus wide-angle flood lighting for total situational awareness; low battery indicator for remaining energy status; windage and elevation bore sight adjustment screws; user selectable modes; adjustable laser and illuminator power; optional auto-on and boost mode. The universal rail mount on the TOR Fusion will fit all pistols that have a Picatinny or Weaver style rail forward of the trigger guard. This design of the TOR Fusion allows for optimum positioning of the laser so that the fire buttons are easily accessible for a wide range of users.
