Description
These Trijicon Suppressor/Optic Height sights solve a problem that trips up a lot of folks running a can or a red dot on their M&P: standard-height sights disappear behind a suppressor and sit too low to co-witness with an optic. This set fits the Smith & Wesson M&P C.O.R.E. and M&P M2.0 Optics Ready pistols, and the taller blades give you a real sight picture no matter what you've got hanging off the muzzle or bolted to the slide.
This particular configuration runs a white front outline with a green tritium lamp up front and a plain metal rear, all lit by green tritium. That means a clean, high-contrast dot to focus on in daylight and a battery-free glow when the lights drop. The rear notch is a square style measuring 0.14 inches wide, and the front blade sits at 0.110 inches, a proven combination for lining up fast without the front post crowding out your target.
What Makes the Trijicon Suppressor Sights Tough Enough to Live On a Slide
Durability is where Trijicon earns its reputation. Each tritium lamp is sealed inside an aluminum cylinder, cushioned with silicone rubber to soak up recoil, and capped with a sapphire jewel that spreads the light evenly while shielding the glass from solvents and punctures. It's the same shock-resistant build that made the original Bright & Tough sights a go-to, just stretched taller for suppressor and optic clearance. The green tritium lamps carry a 12-year glow warranty from the date of manufacture.
Fitting These Night Sights to Your M&P
The overall rear height comes in at 0.492 inches and the overall front blade height at 0.378 inches, purpose-built to clear a suppressor and co-witness with the Trijicon RMR. Trijicon recommends professional installation, and honestly a proper sight pusher and a gunsmith's hand will save you headaches, since these are pressed into the dovetails and the rear uses a set screw to lock things down.

Frequently Asked Questions
Will these Trijicon suppressor height sights co-witness with an RMR?
Yes. These sights are built tall specifically to serve as backup iron sights alongside a slide-mounted red dot like the Trijicon RMR. The extra height lets you see the sight picture through or around the optic window if the dot ever goes down.
Which pistols do these sights fit?
This set is cut for the Smith & Wesson M&P C.O.R.E. and M&P M2.0 Optics Ready models. Double-check that your slide is the optics-ready or C.O.R.E. version, since the dovetail cut differs from a standard M&P slide.
Do the tritium lamps need batteries, and how long do they last?
No batteries at all. The green tritium lamps glow on their own using a sealed phosphor-filled glass vial, so they're always ready in low light. Trijicon warrants the green tritium to glow for 12 years from the date of manufacture, though the light does gradually dim over time as tritium naturally dissipates.
Can I install these sights myself?
Trijicon recommends professional installation. These press into the slide dovetails and the rear locks down with a set screw, so a proper sight pusher and a steady hand make the job far easier and safer for the sights. A gunsmith can knock it out quickly if you'd rather not risk marring your slide.
