Glock Oem Rear Night Sight G42 G43 6.1mm Tritium Slim Rear Sight

The Glock OEM Rear Night Sight G42/G43 is a slim 6.1mm rear sight engineered for subcompact Glock pistols in the GLOCK 42 and GLOCK 43 series, delivering contrasting tritium inserts that make target alignment fast and intuitive in low-light and no-light scenarios. As a factory-designed sight, it maintains the OEM footprint and sight radius so concealment-minded shooters and carry instructors can upgrade night visibility without altering holster fit or point of impact, while the narrow 6.1mm profile minimizes snag during draw from small carry rigs. Hunters who carry a compact pistol for woods or camp defense, law-enforcement officers working late shifts, and everyday concealed carriers will appreciate the consistent sight picture and durable construction built to Glock's tolerances. The glow of the tritium insert requires no batteries and provides a reliable aiming reference when ambient light fails, and installation follows standard rear-sight fitting for the G42/G43 platform, making this an efficient choice for those seeking proven night-sight performance on Glock subcompact handguns.
