Description
Stock polymer sights are fine until the sun goes down. These Trijicon Bright & Tough Night Sights swap them out for a self-luminous three-dot setup that stays visible whether you're on the range at noon or clearing a dark hallway at 2 a.m. The tritium lamps glow on their own with no batteries to check or replace, and the white outlines around each dot keep the picture crisp in daylight too. Owners of the P99 and PPQ line consistently point out the jump in speed and accuracy over the factory sights, both in bright light and pitch black.
What Makes These Trijicon Sights Tough
The name isn't just marketing. Each tritium lamp sits capped with a sapphire jewel that spreads the light evenly and shields it from cleaning solvents and punctures. Those lamps ride inside aluminum cylinders with silicone rubber cushioning underneath, so recoil and repeated slide cycling don't rattle them loose. The bodies are metal instead of the plastic that ships on the gun, which is exactly why so many people upgrade in the first place. Green lamps carry a 12-year warranty from the date of manufacture, so you're looking at more than a decade of reliable glow.
Fit for the Walther P99, PPQ, and PPQ M2
This set is cut specifically for the Walther P99, PPQ, and PPQ M2, front and rear. Front sight width runs 0.142 inches with a height of 0.244 inches, and the rear sits at 0.331 inches tall. A handy detail: you'll want to save the windage adjustment screw from your factory rear sight to reuse in the new one.
Installing the Night Sights at Home
Trijicon recommends professional installation, and a gunsmith is never a bad call. That said, plenty of Walther owners handle this one at the bench. The rear slides into the dovetail and locks with a screw from the top, while the front uses a small hex nut that benefits from a proper sight tool and a drop of blue thread locker. Take your time getting that tiny front screw started, run a quick zero check afterward, and you're set.

Frequently Asked Questions
Will these Trijicon night sights fit my Walther PPQ M2?
Yes. This set is made for the Walther P99, PPQ, and PPQ M2, covering both the front and rear. It also fits the PPQ chambered in .45 ACP. As long as you have one of those Walther models, this is the correct set.
Do the tritium sights need batteries?
No batteries required. The green glow comes from self-luminous tritium lamps that produce their own light around the clock. The green lamps are warranted for 12 years from the date of manufacture, so you get well over a decade of dependable low-light visibility.
Can I install these Walther night sights myself?
Trijicon recommends professional installation, and a gunsmith with a sight pusher makes it painless. Many Walther owners do it at home, though. The rear drops into the dovetail and locks with a top screw, while the front uses a small hex nut that goes easier with a proper sight tool and a dab of blue thread locker. Save the windage screw from your factory rear sight to reuse in the new one.
How do these compare to the factory Walther sights?
The biggest differences are the metal construction and the added low-light performance. The factory sights are polymer with no illumination, while these give you a crisp three-dot tritium picture day or night. Owners regularly report faster target acquisition and a noticeable bump in both daytime and nighttime accuracy after switching.
