Trijicon 600465 Bright & Tough Night Sights - 3-Dot Tritium Green/White Outline - Sig Sauer .40 S&W/.45 ACP #6 Front/#8 Rear

The Trijicon Bright & Tough Night Sights are self-luminous 3-dot iron sights engineered to dramatically improve low-light pistol accuracy. This set is purpose-built for Sig Sauer .40 S&W and .45 ACP pistols and is calibrated to deliver a correct sight picture across both calibers, making it a versatile upgrade for shooters running either cartridge.

Each sight features a tritium-filled lamp surrounded by a crisp white outline ring, producing instant visibility in darkness without the need for batteries or an external light source. The green tritium glow paired with the white-outlined three-dot pattern has long been the standard for duty and defensive pistols, and Trijicon rates these sights as capable of improving nighttime hit capability by as much as five times compared to standard iron sights.

The sights are built around a rugged steel frame finished in black and use a #6 front with a #8 rear configuration matched to the host pistol. This set is a direct fit for Sig Sauer models including the P220, P229, P240, P245, P938, and Pro233, replacing factory sights with a brighter, more durable aiming system designed for the rigors of concealed carry, duty use, and home defense.

Designed as a drop-in night-sighting solution, this Trijicon set gives the shooter a fast, intuitive aiming reference in any lighting condition, with no batteries to replace and no switches to operate.
