Hi-Viz
A HIVIZ Tritium Night Sight Set for Ruger Security 9 pistols upgrades your carry gun with sights that work in both daylight and darkness. The set includes matched front and rear sights, pairing a bright white halo design for fast target acquisition in good light with tritium inserts that glow in low-light and no-light conditions. If you carry your Security 9 for personal defense or duty, reliable sights that don't depend on a flashlight or smartphone light are genuinely worth the investment.
Tritium night sights are a proven upgrade for defensive handguns. The tritium itself is self-luminous—no activation, no batteries—and holds its glow for years. The white halo around each tritium insert gives you a daylight sight picture with high contrast, so you're not trading low-light performance for shooting accuracy at the range or in a gunfight. That combination is harder to find than it sounds, and it's why tritium sights remain the standard for serious shooters who need their gun to work when it's dark.
These sights are purpose-built for the Ruger Security 9, so installation is straightforward if you're comfortable punching out the original sights or prefer to have a gunsmith handle it. Either way, you'll have night sights that match your pistol's geometry and don't require modification to the gun itself.
| Product Type | Night Sight Set (Front & Rear) |
| Firearm | Ruger Security 9 |
| Sight Style | Tritium with White Halo |
| Includes | Front Sight, Rear Sight |
Yes—this set is specifically made for the Ruger Security 9. They are a direct fit with no modifications required.
Tritium has a half-life of about 12 years, meaning the glow gradually fades but remains visible well beyond that timeframe for practical defensive use.
No. Tritium is self-luminous and glows continuously without batteries, charging, or any activation step.
The set includes a front sight and rear sight—everything needed for a complete night sight upgrade.
