HiViz FastDot H3 Sight Set for Sig Sauer P320/P365 Features The HiViz FastDot H3 Sight Set combines a red fiber optic front sight with a green tritium rear sight giving shooters a fast single dot sight picture that stays visible in bright daylight through the fiber optic front and low light through the encapsulated tritium rear. This dual technology approach means the sight set performs around the clock without requiring a battery or activation switch of any kind. All steel construction stands up to holster wear and repeated use far better than a plastic sight body would. HiViz backs its tritium illumination with a 12 year warranty against failure resulting from defects in workmanship or material during normal use. Designed specifically for the Sig Sauer P320 and P365 with fixed sights this set is not intended for optics-ready models that already carry a red dot since the low profile height is calibrated for co-witnessing with iron sights alone. The sight set fits directly into standard holsters without requiring a different holster cut. HiViz built its FASTDOT line around the idea of a single easily-picked-up dot rather than a traditional three-dot pattern helping shooters acquire the sight picture more quickly under stress. The HiViz FastDot H3 Sight Set for the Sig Sauer P320/P365 is available for sale at GrabAGun for shooters who want dependable always-visible sights on their carry pistol.
