The Hi-Viz LiteWave H3 tritium and fiber optic sight set is a versatile aiming solution for your S&W M&P Shield, engineered to deliver fast sight acquisition in low light and bright daylight alike. This sight set pairs self-illuminating tritium in the front sight with a fiber optic rear, creating a dual-illumination system that keeps your sight picture sharp whether you're training at dawn, in dark indoor ranges, or in daylight defensive scenarios. The green tritium front with white outline and orange fiber optic rear combination provides excellent contrast and visibility across changing light conditions—no batteries required for the tritium element, making it one of the most reliable upgrades for carry and home defense pistols.
Built entirely from steel, the LiteWave H3 is designed to withstand hard use. These sights maintain factory sight heights and fit standard holsters, so you can drop them onto your Shield without worrying about holster compatibility issues. Whether your Shield is chambered in 9mm or .40 S&W, this set will fit—just verify your model isn't a CORE variant or long-slide before ordering.
The combination of tritium and fiber optic technology in a single sight set means you get both always-on illumination (from the tritium) and daylight brightness (from the fiber optic), eliminating the compromise most shooters face when choosing between one or the other. For a carry gun that spends half its life in a holster and half being trained with, this dual approach makes real sense.

Yes, the LiteWave H3 is designed for the standard M&P Shield in any caliber. However, they will not fit the CORE variant or long-slide models, so verify your pistol's exact model before purchasing.
No. The tritium element in the front sight is self-illuminating and requires no external power source. The fiber optic rear sight gathers ambient light passively. Together, they ensure reliable illumination in nearly any lighting condition without battery dependency.
No. These sights maintain factory sight heights for the M&P Shield and are designed to fit standard holsters, so your existing holster should function without modification.
This sight set gives you the best of both: tritium provides reliable illumination in darkness without any external light source, while the fiber optic rear gathers available light for exceptional brightness in daylight. The combination eliminates the trade-off you'd make choosing one or the other alone, making it ideal for a defensive carry gun that may be drawn in any lighting condition.
