Trijicon 600757 Bright & Tough Night Sight Set 3-Dot Tritium Green with Black Outline Front Rear Black Frame for 1911 with RMR SRO Cuts CA428-C-600757 UPC 719307212428
Product Description
The Trijicon Bright & Tough Night Sight Set (CA428-C-600757 / 600757) is a self-luminous, three-dot tritium iron sight system engineered specifically for 1911 pistols equipped with Trijicon RMR and SRO optic cuts. Designed to provide standard suppressor-height co-witnessing through reflex optic windows, these high-profile iron sights ensure instantaneous backup indexing in the event of primary red dot optic battery failure or lens damage.
Featuring Swiss-made green tritium lamps housed in protective aluminum cylinders and cushioned by silicone rubber shock mounts, the Bright & Tough series is built to withstand violent slide acceleration and heavy recoil impulses. Subdued black outlines surrounding each green tritium vial minimize sight picture clutter, allowing operators to maintain focus on the optic reticle without visual distraction during daylight operations while providing clear, self-luminous alignment in complete darkness.
Precision CNC-machined from solid steel with a corrosion-resistant black finish, the front blade incorporates a sapphire jewel cap that evenly distributes light from the tritium cell while shielding the lamp from solvents and debris. Engineered for hard-use duty, defensive carry, and tactical 1911 setups, Trijicon delivers industry-leading low-light reliability backed by a 12-year tritium lamp warranty.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Designed specifically for 1911 slides machined with Trijicon RMR/SRO adapter cuts or integrated slide mounts. Requires standard 1911 sight installation tools or dovetail filing for proper armorer fitment.
- Perform a complete firearm safety check: drop the magazine, lock the slide rearward, and visually inspect the chamber to verify zero live rounds are present.
- Remove the existing iron sights and clean the front and rear sight dovetail slots thoroughly to remove machine oil and burrs.
- Measure dovetail tolerances; use a fine armorer sight file to fit the sight bases gently if hand-fitting is required (do not force sights with excessive impact).
- Drift the rear sight and front sight into their respective slide dovetails using a dedicated universal sight pusher tool.
- Verify sight alignment and height co-witnessing through your mounted Trijicon RMR or SRO red dot sight window.
- Apply medium-strength threadlocker (Blue Loctite 242) to the rear set screw (if applicable) and torque securely.
Key Features
- RMR / SRO Co-Witness Height: Tall optical profile provides a reliable lower 1/3 or absolute co-witness through Trijicon red dot lenses.
- Self-Luminous Green Tritium Lamps: High-grade tritium vials illuminate automatically in low-light and total darkness without batteries.
- Subdued Black Sight Outlines: Non-reflective black outlines reduce visual distraction during daytime reflex sight aiming.
- Protective Sapphire Jewel Caps: Distributes tritium light evenly while sealing internal lamps against cleaning chemicals and impact.
- Shock-Mounted Metal Housings: Tritium vials are suspended in silicone rubber inside protective aluminum sleeves to resist recoil shock.
- Machined Steel Construction: High-strength steel bodies built to withstand hard tactical use and one-handed slide manipulation.
