Glock Oem Rear Night Sight G42/g43

The Glock OEM Rear Night Sight G42/G43 is the factory-standard luminous aiming solution designed specifically for Glock's slim-profile compact pistols. Built for concealed carry shooters who need reliable low-light target acquisition without adding bulk or weight, this rear night sight integrates Glock's proven tritium lamp technology into a rugged, combat-proven package. Whether you're upgrading from factory plastic sights or completing a night sight set, this OEM component delivers the precision and dependability that professional shooters and civilians alike depend on for defensive carry.

This rear sight features a self-illuminating tritium lamp that provides constant visibility in darkness without requiring batteries or activation. The compact design is engineered to fit the dovetail cut of G42 and G43 frames without modification, ensuring proper alignment and zero retention. At just 0.06 lbs and measuring 0.75 inches in height with a 0.5-inch width, the sight maintains the slim profile these subcompact pistols are known for, critical for IWB and appendix carry configurations where bulk compromises concealment and comfort.

This OEM rear night sight is ideal for G42 (.380 ACP) and G43 (9mm) owners seeking factory-backed reliability and compatibility. Installation requires standard dovetail sight removal tools and takes minutes; no gunsmithing or modifications to the frame are necessary. Pair it with a matching OEM Glock front night sight to complete your low-light sighting system, or integrate it into existing setups where front sight selection may differ based on your specific carry or training needs.
