Description
The Trijicon HD Night Sight Set turns your 1911 into a gun you can run with confidence when the light gets ugly. The front sight carries a green tritium lamp ringed in bright yellow photoluminescent paint, and it sits on a taller blade so your eye snaps to it instantly. Pair that with a blacked-out rear and you get a sight picture that stays fast and uncluttered, whether you are drilling paper at the range or reaching for a nightstand gun at 2 a.m.
Why the HD Night Sight Design Works
The whole idea here is front-sight focus. That yellow ring glows after soaking up light and helps the front dot pop against the plain black rear, so your eye naturally lands on the aiming point instead of hunting for it. The rear notch is a wide U-shape that frames the front blade cleanly and gives you fast, precise alignment in bright sun, fading dusk, or full dark. All three dots run battery-free green tritium, so there is nothing to charge or switch on when you need them most.
Built to Take a Beating
These are not fragile sights. The front and rear are machined from solid steel, and the tritium lamps ride in silicon-cushioned aluminum housings that shrug off recoil round after round. The surfaces are angled and textured to cut glare and boost contrast, which is a detail you notice the first time you shoot into a low sun. Trijicon backs the green tritium with a 12-year warranty, so you know exactly how much service life you are buying.
Fitment for Your 1911 Novak Cut
This CA128Y set is cut specifically for 1911 pistols with the Novak low mount dovetail. It covers a lot of popular 1911 platforms, but keep in mind that Kimber and some Ruger models use their own dovetail geometry and are not a drop-in match. A little fitting is normal with quality steel night sights, so a proper sight pusher and a knowledgeable installer make the job smooth.

Frequently Asked Questions
Will these Trijicon HD Night Sights fit my 1911?
This CA128Y set is made for 1911 pistols cut for the Novak low mount dovetail, which covers a wide range of common models like many Colt and Springfield builds. Kimber uses a different rear cut, and Ruger typically runs its own licensed sights that are slightly smaller, so those are not a direct match. If you are unsure of your slide's dovetail, check with your gun's maker or your gunsmith before ordering.
Do the tritium lamps need batteries or charging?
No batteries and no switches. The green tritium lamps self-illuminate around the clock, so they are always ready in low light and no light. The yellow front ring is photoluminescent, meaning it soaks up ambient light or a quick flashlight hit and glows brighter for a while, which gives the front dot extra pop during the day and in transitional lighting.
Why a yellow front ring instead of white or orange?
The yellow photoluminescent outline is meant to make the front sight jump out against the plain black rear, driving your eye straight to the aiming point. Many people find yellow easy to pick up in bright and mixed lighting. Trijicon offers the same set in an orange front outline if you prefer that contrast instead.
Can I install these Trijicon HD sights myself?
It is doable if you have the right tools, but quality steel night sights usually need some fitting rather than dropping right in. A proper sight pusher for the rear and careful work on the front dovetail make it much easier and safer for the finish. If you are not comfortable with that, a gunsmith can knock it out quickly and get your zero close.
