There's never been anything like the GTO Laser sight! The GTO included a Finger Touch Adapter (FTA) that can be used to activate the laser by touching either side contact with an extended trigger finger. This means there is no manual button that can be accidently switched on, draining the battery. Simply tap the sensor with your finger to activate the laser and tap it again to switch it off.
Additional features include a convenient battery door, simple laser adjustments, and a master kill switch for iron sights practice. Covered by a 5 year limited warranty.
Note: Armalaser FLX strips for instant activation upon naturally gripping your specific pistol model are available separately (product family #1019944411).
