The TTI Ultimate Fiber Optic Sights for GLOCK® were designed to the specifications of Taran Butler and Robert Vogel for the optimum sight picture and brightest fiber optic front sight possible. The fiber optic dot has been moved up to the very top of the front sight so the shooter doesn't get confused with shooting off the top of the dot or a big, thick blade sitting above it, which can cause the shooter to shoot either too high or too low.

The fiber optic bar is NOT partially embedded into the floor of the sight, which means more light reaches a greater portion of the circumference of the rod. The shiny stainless steel screw reflects even more light right to the middle of the rod.The front sight is .235" tall and .115" wide for perfect point-of-impact with the GLOCK® 17, 17L, 19, 20, 21, 22, 23, 24, 34, and 35.The rear is .245" tall. The tighter .125" rear notch helps dramatically when shooting small steel and tight shots at a distance.Rear serrations cut down on glare. Both front and rear sights are billet stainless steel coated with Diamond Black Ion Bond (95 Rockwell hardness) for the highest level of rust resistance and the strongest finish.
