XS Sights 8.1 Inch Tritium Glow Dot Front Sight

XS Sights RV0003N3Y Big Dot Revolver Front Sight is a defensive tritium sight engineered to enhance your defense gun. The sight features a proprietary photoluminescent Glow Dot that absorbs ambient light and glows in low light conditions. The convex dot’s additional surface area increases light absorption, intensifying the charge of the Glow Dot. Designed to be large and highly visible, this sight addresses many issues, from aging eyes to deteriorating vision. The yellow outline offers bright glow in low light, while green is an excellent low light option with very bright glow intensity. XS Tritium Night sights deliver big, bright, and easy-to-see performance day or night for Smith & Wesson revolvers. Pin hole for front sight must be drilled for installation of sight.
