Trijicon 600138 Bright & Tough Night Sights 1911 .125 Tang 3-Dot

The Trijicon Bright & Tough Night Sights (part 600138) are self-luminous 3-dot tritium night sights purpose-built for the Colt 1911 Government with a .125 tang. Each lamp sits in a rugged steel body finished in black, cushioned within silicone rubber, and capped with a sapphire jewel that protects the tritium vial from solvents and impact.

This front and rear sight set features green tritium lamps paired with white outline rings on both the front post and rear sight, producing the classic three-dot aiming picture that's quick to acquire in low light. The tritium inserts glow continuously without batteries, switches, or ambient light, giving shooters a dependable aiming reference around the clock and increasing night-fire accuracy by as much as five times over conventional iron sights.

The 600138 set is engineered to fit Colt Government, 1911, Combat Elite, and Delta Elite pistols made after 1988, along with Para Ordnance P10 and P14 pistols equipped with a stake-in front. Front sight installation uses a stake-in method that typically requires professional fitting, and Trijicon's proven build quality makes this set a popular upgrade for carry, duty, and defensive 1911 platforms.
