Description
Running a suppressor or a slide-mounted red dot on your Glock 17 means your factory irons suddenly sit too low to do you any good. That is exactly the gap this Trijicon set fills. These are taller than standard height sights, giving you a clear point of aim over a can and putting your irons right where you need them when a dot is mounted up front.
The front sight carries a green tritium lamp with a clean black outline, so it stands out in low light but won't distract you in daylight. The rear is a solid metal blade with a square U-notch that lines up fast and holds zero through recoil. Trijicon builds each lamp inside an aluminum sleeve cushioned with silicone rubber and caps it with a sapphire jewel for even light distribution, which is the same battery-free tritium tech that made their Bright & Tough line a standard with law enforcement and military users. The front lamp is warranted to glow for a full 12 years, so there are no batteries to swap and nothing to charge before a night shoot.
Why the Height on These Trijicon Sights Matters
Measuring roughly .365 inch up front and .361 inch at the rear, this set is designed to give you a lower 1/3 co-witness with a Trijicon RMR on a milled slide. That means your irons sit in the bottom third of the optic window, staying out of the way when you're driving the dot but instantly there as a backup if the electronics ever quit. Owners running RMRs, Holosuns, and similar optics consistently report a clean, accurate co-witness and bright, easy-to-find tritium.
Fitment and Install Notes for the Glock 17 Set
Beyond the 17, this set fits a long list of standard-frame Glocks including the 17L, 19, 22, 23, 24, 25, 26, 27, 28, 31, 32, 33, 34, 35, 37, 38, 39 and 45. Keep in mind MOS slides sit the optic higher, so confirm your setup before ordering. Professional installation is recommended since the front sight torques in and the rear drifts into the dovetail. A proper Glock sight tool and a dab of thread locker will get these seated solid.

Frequently Asked Questions
Will these Trijicon suppressor height sights co-witness with an RMR?
Yes. On a milled standard-frame Glock slide, this set gives you a lower 1/3 co-witness, meaning your irons appear in the bottom third of the RMR window. That keeps them out of the way while you're using the dot but ready as a backup if the optic ever goes down. If you're running a factory MOS slide, the optic sits higher, so double-check clearance before ordering.
Do these sights clear a suppressor on a Glock 17?
That's what they're built for. The taller front and rear blades raise your line of sight above a mounted can so you can still line up a proper point of aim when shooting suppressed. They pull double duty as suppressor sights and as backup irons for a red dot.
Why is the front sight black instead of white or colored outline?
The black front outline keeps your daytime sight picture clean and free of distraction while the green tritium lamp still lights up in low light. If you prefer a more visible daytime front, Trijicon also offers this same set with orange and yellow front outlines. This particular part number is the black front version with green tritium.
Can I install these Trijicon sights myself?
Trijicon recommends professional installation. The front sight torques in with a hex screw and the rear drifts into the dovetail, so a proper Glock front sight tool, a rear sight pusher or drift punch, and a little thread locker make the job much easier. Many owners install them at home with the right tools, but if you're not comfortable, a gunsmith can knock it out quickly.
