Rival Arms RARA1B231S SIG Sauer 3-Dot Night Sights - Black | Green Tritium White Ring Front & Green Tritium Black Ring Rear

Night sights transform how you engage your SIG Sauer pistol in low-light conditions—and the Rival Arms RARA1B231S SIG Sauer 3-dot night sights deliver that capability without compromise. These are tritium-powered sights, meaning they glow on their own in darkness, no batteries or external light source required. The front sight features a green tritium tube surrounded by a white ring, while the rear sight pairs green tritium with a black ring. That contrast helps your eye naturally align the sights quickly, whether you're shooting at the range, competing, or carrying for self-defense. If your SIG Sauer is your go-to pistol, upgrading to dedicated night sights is one of the smartest moves you can make.

The three-dot pattern is the most intuitive sight picture for most shooters—front sight in the middle, two rear dots on either side. It's simple, fast, and proven. Tritium sights like these maintain their glow for years without fading, giving you a permanent low-light solution that doesn't wear out or need maintenance. Whether you're practicing after work when light fades or carrying in conditions where darkness is a real possibility, tritium sights keep you ready.

Installation on most SIG Sauer models is straightforward, but we recommend having a gunsmith handle it if you're not experienced with sight installation. These sights are a genuine upgrade over factory plastic or basic metal sights, and they're built to last through thousands of rounds.

Frequently Asked Questions

Will these night sights fit my SIG Sauer pistol?

These sights are designed for SIG Sauer pistols. Confirm your specific model is compatible before ordering, as SIG Sauer uses different dovetail configurations across their lineup. If you're unsure, contact us or consult your pistol's manual.

How long do tritium sights stay bright?

Tritium has a half-life of about 12 years, meaning the glow will be noticeably dimmer after that period. For most shooters, you'll get many years of reliable low-light performance before any noticeable fading occurs.

Can I use these sights during the day?

Yes. Tritium sights work in daylight—you just won't see the glow. The white and black rings on these sights aid sight picture alignment in all light conditions, making them an all-around upgrade, not just a night-only tool.

Do I need a gunsmith to install these?

Professional installation is recommended unless you have experience with sight installation and the proper tools. Improper installation can damage your slide or compromise sight alignment, so don't skip this step if you're uncertain.
