The Hi-Viz FASTDOT H3 Night Sights GSG320FD21 is a pistol night sight set designed for continuous visibility on Sig Sauer P320 and P365 pistols with fixed sights. This sight system combines tritium and fiber optic elements for 24-hour illumination.

The Hi-Viz FASTDOT H3 Night Sights GSG320FD21 fits Sig P320 and P365 models chambered in 9mm with non-optic-ready fixed sight configurations and includes both front and rear sight components. The front sight uses a red illumination element, while the rear sight uses green for contrast. The low-profile design integrates tritium and lightpipe technology without external power sources. This model is configured as a matched front and rear set for proper alignment. In typical setups, it provides a consistent sight picture across lighting conditions. This product is used for handgun sight replacement and is suitable for range use and low-light shooting applications.
