Night Fision GLK003007YGZ Tritium Night Sights for Glock 42/43/43X - Green Tritium Yellow Outline Front / Green Tritium Black Outline Rear

The Night Fision GLK003007YGZ Perfect Dot night sight set upgrades the Glock 42, 43, and 43X micro-compact pistols with self-illuminating tritium for fast, instinctive target acquisition in low light or no light. Engineered as a direct OEM replacement, the sights drop into the factory dovetails without modification, instantly boosting the pistol's carry-ready capability.

The front sight carries a square profile with a green tritium lamp ringed by a yellow outline for high-contrast visibility, while the rear sight uses a U-notch paired with a green tritium lamp and a black outline. The two-tone color scheme helps the eye lock onto the front sight faster in transitional light, while the blacked-out rear keeps visual focus forward. Tritium illumination is self-powered, requiring no batteries or ambient light to glow, and Night Fision loads each vial with roughly 30% more tritium than typical competing night sights for a brighter, more defined nighttime picture.

Built on a rugged steel sight body finished in black, the GLK003007YGZ is constructed to handle the recoil of daily concealed carry. The tritium vials are held by Night Fision's patented injection-molded sleeve and capped with a domed lens that produces a crisp glow rather than a fuzzy halo. The set ships complete with both front and rear sights ready for installation on the slim Glock 42, 43, or 43X.
