Frequently Asked Questions
Will these sights fit my S&W M&P 9 Shield EZ without gunsmithing?
The HiViz LightWave H3 (model 9EZN321) is purpose-built to fit the S&W M&P 9 Shield EZ and is designed as a drop-in replacement for the factory sights. While basic installation tools may be needed (such as a sight pusher or nylon punch), no permanent modifications to the pistol are required. Many shooters complete the swap at home, though a qualified gunsmith can also install them quickly.
How long does the tritium glow last, and will the fiber optic still work in daylight?
Tritium is a naturally decaying element with a half-life of approximately 12 years, so your sights will remain usably bright for a decade or more under normal carry conditions. The fiber optic element collects ambient light and actively glows bright green in daylight and well-lit environments, while the tritium takes over in darkness — giving you the best of both technologies in a single sight package.
Are these sights compatible with holsters designed for the standard M&P 9 Shield EZ?
Because the LightWave H3 sights are designed to maintain a profile close to the factory dimensions of the Shield EZ, most standard holsters will remain compatible. However, some slim or form-fitted kydex holsters with tight sight channels may require adjustment. It is recommended to test fit your holster after installation and consult your holster manufacturer if clearance is a concern.
