The Trijicon HD Night Sight Set in yellow front outline is built for large frame MOS Glocks that run a red dot up top. The taller MOS-height sights sit high enough to co-witness through your optic window, so you always have a backup sight picture if your dot goes dark or you just prefer irons for a given shot. That combination of daytime speed and nighttime glow is what made the HD line a go-to upgrade for defensive and duty guns.
The front blade is taller and wrapped in a photoluminescent yellow ring around a green tritium lamp, which is what your eye locks onto in a hurry. The yellow outline soaks up ambient light and pops in daylight, dusk, and everything in between, so you get fast front sight acquisition even in that tricky transitional lighting where regular sights wash out. The rear is blacked out with a wide U-shaped notch, letting the front dot stand alone instead of getting lost in a sea of three glowing dots.
Each tritium lamp is capped with a sapphire jewel that spreads the light evenly and shields the vial from solvents and impact. There's no battery to charge or switch to flip, the sights just glow on their own, and the green tritium carries a 12-year warranty from the date of manufacture. The rear sight also has a steeply hooked front face, which gives you an edge to rack the slide one-handed against a belt or boot heel if a hand is ever out of commission.
This set is cut for large frame Glock models including the 20, 21, 29, 30, 36, 40, and 41, covering S and SF variants and MOS-equipped guns. Trijicon recommends professional installation with a proper sight pusher, since these are pressed into the dovetails and the front is secured from below. If you're not comfortable driving sights yourself, any competent gunsmith can knock this out quickly.
Yes. This set uses the taller MOS-height rear and front, which are built to sit high enough to be seen through the red dot window. That gives you a backup iron sight picture if your optic ever loses power or you want to confirm your hold.
No batteries at all. The glow comes from self-powered green tritium lamps that light up on their own in low light. Trijicon backs the tritium with a 12-year warranty from the date of manufacture.
It comes down to the color of the photoluminescent ring around the front tritium lamp. This set uses a yellow outline, while the same sight is also offered with an orange front. Both use green tritium and the same blacked-out rear, so the choice is mostly about which color your eye picks up fastest.
This set is cut for large frame Glocks, covering models 20, 21, 29, 30, 36, 40, and 41, including S and SF variants and MOS-equipped pistols. Double-check your slide cut before ordering, since standard frame Glocks use a different set.
