There's never been anything like the GTO/FLX series Laser sight! The FLX allows the GTO to activate instantly by normally gripping the pistol. No reaching for a switch or awkward button on the grip. FLX's are made from an ultra-thin, ultra-strong NASA-used polymer with 3M adhesive backing. They will not harm the pistol finish and are cleaning solvent-resistant.
If you prefer a more traditional laser activation style, the GTO also included a Finger Touch Adapter (FTA) that can be used in place of the FLX. Using the FTA, you can activate the laser by touching either side contact with an extended trigger finger.
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.
