Trijicon 601140 Suppressor/Optic Height Night Sights Green Tritium White Outline - Glock 42/43/43x/43e/48

The Trijicon 601140 Suppressor/Optic Height Night Sights are purpose-built iron sights designed for Glock 42, 43, 43x, 43e, and 48 slim-frame pistols. The taller sight profile is engineered to clear the silhouette of a mounted suppressor and provides a proper sight picture through pistol-mounted red dots such as the Trijicon RMRcc, making this set an excellent choice as primary iron sights on a suppressed carry pistol or as a backup iron sight (BUIS) for a red-dot-equipped handgun.

Each set features three-dot tritium illumination with green tritium lamps in both the front and rear blades. The front sight carries a white outline and the rear sight carries a white outline for fast daylight acquisition, while the tritium inserts deliver a battery-free glow for reliable low-light and nighttime use. The lamps are housed in protective aluminum cylinders cushioned by silicone rubber that absorb recoil and impact without cracking the tritium vials.

Trijicon designed this set specifically for the slim-frame Glock slide, with sight geometry that co-witnesses through the RMRcc mounting plate to keep the iron sight picture visible alongside a mounted red dot. Front blade width measures 0.144" with an overall front blade height of 0.503"; rear notch width is 0.15" with an overall rear height of 0.554".

The 601140 brings Trijicon's signature ruggedness and dependable aiming reference to slim-frame Glock pistols set up with suppressors or red dot optics.
