The TOR Mini features a Type III hard-anodized machined-aluminum housing and rail mount. It is dustproof and splash-proof to IP54 standards. The TOR Mini is a direct diode type allowing it to operate in extreme cold weather. Other features include left and right fire buttons for ambidextrous use, constant power drive that ensures the laser output remains constant throughout the life of the battery, low battery indication, as well as windage and elevation bore sight adjustment screws. The universal rail mount on the TOR Mini will fit all pistols that have a Picatinny or Weaver style rail forward of the trigger guard. The TOR Mini features adjustable laser power with multiple settings (low, medium, high and high pulse) which are easily set by the user. It will also remember the chosen setting until it is reset, even if the battery is removed or replaced. The TOR Mini also has an internal accelerometer that senses the position of the pistol and when the optional Auto-On feature is activated the laser will turn on when the pistol is drawn from a holster and brought up level. This feature will also work when the pistol is picked up from lying on its side.
