The Meprolight Tru-Dot adjustable tritium night sight set for S&W K, L, N-Frame revolvers brings reliable low-light performance to your wheel gun without batteries or external power. Built with all-steel construction, these sights house Meprolight's proven TRU-DOT tritium lamp design, which glows continuously in darkness and dim conditions—ideal for defensive carry, night hunting, or any situation where you need fast target acquisition when the sun goes down. The red front insert provides a clean sight picture during daylight while the tritium does the work when light fails.
Installation is straightforward: the front sight replaces your factory colored insert, while the rear sight assembly includes a new leaf, screw, and nut for S&W revolvers. Once mounted, both front and rear sights adjust independently for windage and elevation, letting you zero exactly where your shots go. The positive, all-steel detents hold adjustments solid—they won't drift from recoil, hunting conditions, or daily carry.
If you're carrying a K, L, or N-frame Smith & Wesson revolver and want to move confidently into low-light scenarios, these Meprolight sights are built to stay put and stay visible when it counts. Rugged, field-proven, and designed for the users who trust their gear in the dark.

Frequently Asked Questions
Will these sights fit my Smith & Wesson revolver?
These Meprolight Tru-Dot sights are designed for S&W K, L, and N-Frame revolvers with dovetail mount. The set includes everything needed for installation, including a new rear leaf, screw, and nut. Check your specific revolver model to confirm it uses a dovetail-mounted sight system.
Do I need batteries for the tritium to work?
No. Tritium is self-illuminating and requires no batteries, external power, or charging. It glows continuously in low-light and dark conditions for the life of the tritium element.
Can I adjust these sights after installation?
Yes. Both the front and rear sights are fully adjustable for windage and elevation. The all-steel detents hold your adjustments solid under recoil and field use.
What does the red front insert do?
The red front insert provides a clear, conventional sight picture in daylight and normal lighting. The tritium lamp illuminates when ambient light fades, making the sight visible in darkness without losing your daytime zero.
