Description
Trijicon's HD Night Sights have earned their reputation as one of the best defensive iron sight upgrades you can bolt onto a carry gun, and this set (part 601170) is cut specifically for the Smith & Wesson M&P CORE platform. The front blade wears a high-visibility orange photoluminescent outline that glows after light exposure, while the black-outlined rear stays subdued so nothing competes with your front sight. Both dots run green tritium, so you get a usable sight picture in bright daylight, that awkward transitional dusk, and pitch black.
What Makes the HD Set for the M&P CORE Different
The magic here is the front sight. Trijicon tops the tritium lamp with a domed sapphire jewel that focuses the glow into an aiming point that reads about twice as bright as a standard tritium dot. That jewel also protects the lamp from cleaning solvents and knocks. The rear uses a wider U-shaped notch that's angled and serrated to cut glare, which naturally pulls your eye toward that bright orange front dot instead of fighting for attention.
Built for Optics-Ready CORE Slides
Because this set is designed around the M&P CORE, it works well as a backup iron sight setup for shooters running a slide-mounted red dot like the Trijicon RMR or a Holosun. Many CORE owners want irons that line up with their optic, and this taller front blade helps you see the sights and get a lower-third or absolute co-witness depending on your dot's cut. If your red dot ever goes dark, you've still got a fast, glowing sight picture to fall back on.
Durability You Can Count On
Each tritium lamp sits inside a protective aluminum cylinder with a silicone rubber cushion to soak up recoil, so these hold up to real range time and daily carry. The green tritium lamps carry a 12-year warranty from the date of manufacture. Installation calls for a sight pusher and a bit of know-how, so most folks have a gunsmith knock them in or use the right tool at home.

Frequently Asked Questions
Will these Trijicon HD sights fit my Smith & Wesson M&P CORE?
Yes, this set (601170) is cut specifically for the Smith & Wesson M&P CORE optics-ready platform. It's not the same as the standard M&P dovetail set, so matching the CORE-specific part number matters. If you're unsure which M&P variant you have, check your slide markings or reach out and we'll help you confirm the fit.
Can I co-witness a red dot with the Trijicon HD set on my CORE?
Since these are built for the optics-ready CORE slide, the taller front blade helps you use them as backup irons alongside a slide-mounted dot like an RMR or Holosun. Depending on your specific optic's cut, you'll typically land in a lower-third or absolute co-witness. That gives you a reliable fallback sight picture if your red dot ever loses power.
Do the tritium sights need batteries and how long do they last?
No batteries at all. The green tritium lamps are self-luminous and glow on their own, and Trijicon warranties them for 12 years from the date of manufacture. The orange front outline also uses photoluminescent paint that charges up in light for extra daytime visibility.
Can I install the HD night sights myself?
You can, but Trijicon recommends professional installation and it's the smart move for most folks. A proper sight pusher makes the job clean and keeps you from marring the slide or dots. If you don't have the right tool, any gunsmith can knock these in quickly.
