Description
The Hi-Viz LiteWave H3 sight set was built to solve one problem cleanly: seeing your sights in every light condition. It does that by combining encapsulated tritium with Hi-Viz's LitePipe fiber-optic technology, so the front dot glows green in the dark and lights up bright in the sun. The front sight wears a white ring around that green dot for a crisp aiming point, while the orange rear helps your eye split the difference and line things up fast. That color contrast is the whole point, and it works whether you're on the range at noon or reaching for the pistol in a dark room.
What the LiteWave H3 Brings to Your M&P
These are all-steel sights, front and rear, so they hold up to hard use, holster wear, and the kind of abuse a carry gun sees. They're cut to factory sight height, which matters more than folks realize: it keeps your point of impact where it should be and lets you keep running the same holsters and accessories you already own. This set fits Smith & Wesson M&P full-size and compact models across all calibers in the standard configuration.
Fitment Notes Before You Order the LiteWave H3
One thing worth double-checking before you buy: this set does not fit the M&P CORE, the M&P 22, or long slide models. If you're running a standard M&P full-size or compact, you're good to go. The tritium carries a 12-year warranty against loss of illumination, dated right on the sight so you always know where you stand.
Between the 24-hour glow, the steel build, and the fast-acquisition color scheme, the LiteWave H3 is a smart upgrade over plain factory sights for defense, duty, or just faster follow-ups at the range. Pressing these in is straightforward with the right tools, though a gunsmith or a sight pusher makes the job painless if you'd rather not fight the rear dovetail.

Frequently Asked Questions
Will the LiteWave H3 fit my M&P?
This set fits Smith & Wesson M&P full-size and compact models in all calibers in the standard configuration. It does not fit the M&P CORE, M&P 22, or long slide versions. If you've got a standard full-size or compact M&P, you're set.
How do the LiteWave H3 sights stay visible at night?
Each sight uses encapsulated tritium, which glows on its own without needing to be charged by a light source. Paired with the LitePipe fiber-optic tech that shines in daylight, you get a usable sight picture around the clock. The tritium is backed by a 12-year warranty against loss of illumination.
Are these sights the same height as my factory M&P sights?
Yes, the LiteWave H3 is cut to factory sight height. That keeps your point of impact consistent and means your existing holsters and accessories will still fit the way they did before.
Can I install the LiteWave H3 sights myself?
Plenty of people do, but the rear sight sits in a dovetail that usually needs a sight pusher or a brass punch and a steady hand to move. If you don't have the tools or the patience, a gunsmith can knock the install out quickly. Take your time so you don't mar the steel or the slide.
