Trijicon 600578 HD Night Sights Green Tritium Yellow Outline - Sig Sauer P220/P229/P240 #6 Front/#8 Rear

The Trijicon 600578 HD Night Sights upgrade Sig Sauer P-Series duty pistols with self-illuminating aiming points built for fast target acquisition in any light. These 3-dot tritium night sights use rugged steel components in a black finish, configured as a #6 front / #8 rear set.

The front blade sits taller than a factory unit for an improved sight picture, pairing green tritium with a yellow photoluminescent outline ring that draws the eye to the aiming point in marginal daylight. The rear uses green tritium lamps behind a black-painted U-notch outline for a clean three-dot picture under night-vision-friendly illumination. Drop-in fit for Sig Sauer P220, P229, P240, P245, P938, and Pro 233 slides calibrated for 40 S&W and 45 ACP, the front blade measures 0.144 in wide by 0.289 in tall, with the rear notch at 0.309 in tall.

Trijicon's HD Night Sight line is built as a direct replacement for shooters who want reliable, battery-free aiming on a carry or duty pistol. Tritium gas-filled lamps glow through the night without switches, batteries, or any ambient-light charging, giving a true 24-hour sighting solution the moment the gun leaves the holster.
