Description
The Meprolight Tru-Dot set is one of the easiest low-light upgrades you can make to a Sig P-Series pistol. It swaps your factory irons for a self-illuminated three-dot system that reads the same in bright sun as it does in a pitch-dark room, so there's no mental switch to flip when the lighting changes. The front dot glows green with a white outline, while the rear runs orange with a matching white outline. That color split is intentional. Your eye naturally locks onto the green front dot and treats the orange rear as a reference frame, which speeds up how fast you get on target.
What Makes the Tru-Dot Sights Work in the Dark
The glow comes from sealed tritium vials, not phosphorus paint, so there's nothing to charge with a flashlight and no batteries to swap. They're just on, around the clock, and Meprolight backs the tritium illumination with a 12-year guarantee. Tritium is a proven, well-established night sight technology that law enforcement and military users have leaned on for decades, and Meprolight builds a big share of the world's OEM handgun sights. If you've ever fumbled for a light while trying to line up on a target in the dark, this is the fix.
Built to Take a Beating
These aren't flimsy replacement parts. The Tru-Dot sights ride on a steel frame with a black finish and a snag-free profile that clears leather and Kydex without hanging up on the draw. The rear features a square notch that pulls your focus forward to the front post, exactly the sight picture most defensive and duty shooters want.
Fit and Install Notes for Your Sig P-Series
This set is cut for the standard Sig Sauer P-Series family, including the P226 and P320, and installs as a direct replacement without permanent modifications to your slide. Keep in mind it does not fit the P365X or P365XL. Because both the front and rear sit in dovetails, most folks use a sight pusher tool or hand the job to a gunsmith rather than driving them with a punch and hammer. Do it once, confirm your zero, and you're set.

Frequently Asked Questions
Will these Tru-Dot sights fit my Sig Sauer P226?
Yes, this set is cut for the standard Sig Sauer P-Series family and fits the P226 along with the P320. It installs as a direct replacement for your factory sights without any permanent modifications to the slide. Just note that it is not made for the P365X or P365XL.
Do the Meprolight Tru-Dot night sights need batteries?
No. The glow comes from sealed tritium vials, so there are no batteries to replace and nothing to charge with a flashlight. They stay lit on their own around the clock, and Meprolight guarantees the illumination for 12 years.
How do I install the Tru-Dot sights on my Sig?
Both the front and rear sit in dovetails on the slide. Most people use a sight pusher tool or have a gunsmith do the swap rather than driving them with a punch and hammer, which lowers the risk of marring the sight or slide. Once they're set, confirm your zero at the range and you're good to go.
What's the difference between the green front and orange rear dot?
The color split is intentional and helps your eye do the work faster. Your focus naturally locks onto the green front dot while the orange rear dots act as a reference frame on either side of the notch. That contrast makes it easier to pick up a correct sight picture quickly in both daylight and the dark.
