Glock, Night Sight Rear 6.1mm for Glock 43, 9mm, Matte Finish

The Glock Night Sight Rear 6.1mm for the Glock 43 brings a rugged, low-light aiming solution to the slim single?stack 9mm platform, pairing a 6.1mm rear notch with a tritium insert to maintain a consistent sight picture in dim conditions. Designed for shooters who rely on their Glock 43 for concealed carry and self-defense, this rear night sight fits the model's compact dovetail and holds up to daily carry and range use thanks to hardened steel construction and a matte finish that resists glare and wear. If you run drills at dawn or handle high?stress encounters where ambient light is limited, the tritium element provides a quick reference point to naturally align with the front sight, improving shot acquisition without added bulk. As part of Glock's lineage of rugged, user?focused components for the 43 series, this rear sight installs with basic tools and minimal gunsmithing, making it a practical upgrade for owners who want reliable night performance and a cleaner sight picture for duty, carry, or range applications.
