ScottJ :

There are 2 versions. TDR911 is manual only. The Auto-Laser is the automatic version. You can use it manualy out of the holster and in any other holster that will fit the laser/gun combo. The custom holster that comes with the Auto-Laser has a magnet attached. This magnet is also avilable so you could convert any other holster.
The Auto-Laser is turned on and then inserted into the magnetic field of the holster. At that point the magnetic field disconnects the power source, turning off the laser. On withdraw the laser is removed from the magnetic field and the power comes back on and the laser lights up.


Lets see more Sigma pictures.
