Trijicon SIG HD Night Sight Yellow SG101Y

Sig Sauer pistol owners who want the fastest possible front sight acquisition in any lighting condition have a purpose-built HD solution in the Trijicon HD Night Sights SG101Y. The yellow photoluminescent front outline and HD-specific sight architecture deliver the front sight dominance that serious tactical and defensive shooters depend on - in a sight set specifically fitted for the most widely carried Sig Sauer platforms.

The SG101Y fits Sig Sauer P225, P226, P228, P239, and P320 models - covering the most popular Sig configurations for duty and defensive carry use. The Sig Sauer Night Sight Set SG101Y is purpose-built for these specific models and ensures correct dovetail installation and proper HD sight alignment on the compatible platforms without the fitment complications that generic sight solutions create on platforms they were not specifically designed for. Professional installation is recommended.

The Yellow Night Sights SG101Y yellow photoluminescent paint ring around the taller front sight tritium lamp creates a warm, high-contrast visual reference that draws the eye immediately and naturally to the front sight under stress — faster and more reliably than standard three-dot configurations in transitional lighting and dynamic defensive situations. The taller HD front blade provides greater visual presence above the rear sight, accelerating front-sight acquisition without any deliberate search for the aiming point when time matters most.

Three-dot green tritium illumination provides self-luminous performance in complete darkness, without batteries or any electronics.

The Trijicon night sights SG101Y black rear sight features a wider U-shaped notch that keeps the HD front sight clearly framed and visible in poor lighting conditions. The steeply hooked front surface of the rear sight enables emergency one-handed slide operation for dynamic defensive use.
