Upgrade your Smith & Wesson® M&P® 9 Shield EZ with one of the most advanced iron-sight systems on the market: the HiViz LiteWave H3 sight set. Engineered to combine bright fiber-optic daytime visibility with tritium night illumination, the LiteWave H3 delivers fast sight acquisition in any lighting condition — no batteries required. If you want a rugged, snag-free sight that performs equally well during daylight drills and low-light encounters, this HiViz set is built for it. hivizsights.com+1
Key Benefits — Fast, Clear, All-Hours Sight Picture
24-hour visibility: HiViz fuses its signature LitePipe fiber-optic front with an encapsulated H3 tritium vial, giving you a bright, high-contrast front sight in daylight and a glowing reference at night. That means faster target acquisition and more confident follow-ups whether it’s noon or midnight. hivizsights.com+1
Optimized sight geometry: The front sight features a green LitePipe with a white visibility ring to create an instant focal point, while the rear uses matching green tritium inserts for a clean, three-dot sight picture that helps the eye naturally draw to the front dot. OpticsPlanet
Factory fit & holster compatibility: LiteWave H3 sets are made to duplicate factory sight heights for popular handgun models, so you’ll retain holster fit and carry ergonomics when replacing the stock sights on your Shield EZ. hivizsights.com
Rugged Construction — Made for Duty, CCW, and Range Use
The LiteWave H3 sight set is built from all-steel components and machined to withstand everyday carry, hard use, and environmental exposure. HiViz designs these sights with durability in mind so they hold up to recoil and remain consistent shot after shot — a must for defensive carry and law-enforcement use. palmettostatearmory.com+1
Fast Target Acquisition — Why Shooters Love LiteWave H3
The combination of a high-visibility fiber optic and encapsulated tritium means the sight is visible during bright daylight and still usable in complete darkness. The front green LitePipe framed by a white ring creates a distinct aiming point that the eye locks onto instantly, dramatically shortening sight alignment time during dynamic shooting or stressful encounters. This makes the 9EZN321 ideal for everyday carry (EDC), self-defense, and competitive close-quarters work. OpticsPlanet+1

Installation & Use
The LiteWave H3 sights are engineered for direct replacement of factory sights on the Shield EZ. Many shooters opt for professional installation by a gunsmith to ensure proper dovetail seating and zero retention, but competent home gunsmiths with the right tools can also perform the swap. Once installed, the sight set maintains factory heights—so holster compatibility and point-of-impact remain predictable. hivizsights.com+1

Why LiteWave H3 Stands Out
HiViz’s LiteWave H3 line is a modern evolution of tritium night sights. By combining the brightest available LitePipe fiber optics with long-lasting H3 tritium illumination, HiViz provides a true day-and-night solution that reduces target-acquisition time and increases shooter confidence. The company backs the technology and offers long warranties on tritium performance, making the LiteWave H3 both a reliable and practical upgrade. hivizsights.com+1
