XS Sights R3D Night Sights for Smith & Wesson - Black | Green Tritium Front & Rear Sights

The XS Sights R3D Night Sights for Smith & Wesson deliver fast, reliable target acquisition in low light and darkness without relying on batteries or electronics. Built for shooters who demand dependable sights whether you're training at the range, carrying for self-defense, or working in variable lighting conditions, these night sights use tritium — a self-illuminating radioactive gas that glows consistently for years. The green tritium setup gives you a bright front sight paired with a matching rear sight, so your sight picture stays intuitive and natural.

XS Sights engineered the R3D line specifically to combine visibility with speed. The green outline front sight stands out in daylight while the tritium core provides that glow when the sun goes down. Whether you're shooting at dusk, in a dim indoor range, or on a duty weapon, you'll have a usable sight picture without fumbling for lights or waiting for your eyes to adjust. The black housing keeps the overall profile clean and professional.

Installation requires basic gunsmithing knowledge or a qualified armorer — these are dovetail sights that replace your factory S&W sights. Once installed, tritium sights are maintenance-free and will continue to glow for approximately 10–12 years depending on use and storage conditions. If you shoot a Smith & Wesson pistol and want the confidence that comes from reliable low-light aiming, night sights close the gap between daylight and darkness.

Frequently Asked Questions

What Smith & Wesson models do these sights fit?

The XS Sights R3D Night Sights are designed for Smith & Wesson pistols with dovetail sight cuts. Check your owner's manual or contact our team to confirm compatibility with your specific model.

How long do tritium night sights stay bright?

Tritium sights are self-illuminating and will glow for approximately 10–12 years from the date of manufacture. After that period, the glow fades gradually, but the sights remain usable in daylight.

Can I install these sights myself?

Night sights require removal and installation into your pistol's dovetail cuts. This is a job for a qualified gunsmith or armorer if you're not experienced with sight installation. Improper installation can affect accuracy and safety.

Do I need batteries or electronics?

No. Tritium night sights are completely passive — they require no batteries, charging, or electronic components. The tritium vial glows continuously on its own.
