Frequently Asked Questions
Will these sights fit both the SIG P320 and SIG P365?
Yes. The Meprolight Hyper-Bright HB sights are specifically engineered to fit both the SIG Sauer P320 and P365 platforms. They are a direct-replacement drop-in upgrade that uses the same dovetail dimensions as the factory sights, making installation straightforward with standard sight-pusher tools.
How long will the tritium illumination last?
Meprolight's tritium vials have a functional lifespan of approximately 12 years from the date of manufacture. Over time, tritium naturally decays and brightness will gradually diminish, but the sights will remain usable well beyond that window. The manufacture date is typically marked on the packaging so you can track the service life.
What makes Hyper-Bright different from standard tritium night sights?
Standard tritium sights are primarily designed for low-light use and can be difficult to pick up quickly in daylight. Meprolight's Hyper-Bright sights feature a specially formulated, extra-luminous tritium combined with a vivid colored front sight ring, making them dramatically more visible in broad daylight as well as at night. The result is a true day-night sight that gives you a decisive edge in any lighting condition without needing a separate fiber optic or battery-powered optic.
