Frequently Asked Questions
Will these X-RAY3 sights fit both the P938 and P320 without modification?
Yes, the Sig Sauer X-RAY3 Night Sights in this listing are engineered for direct compatibility with both the P938 and P320 platforms. While installation is a straightforward drop-in process, using a proper sight pusher tool or having a qualified gunsmith install them is recommended to avoid damaging the sight or slide during fitting.
How do the X-RAY3 sights perform in both daylight and low-light conditions?
The X-RAY3 system is designed to perform in all lighting environments. In daylight, the front sight presents a bright, high-contrast aiming point against the clean blacked-out rear notch, keeping your focus on the target. In low-light or darkness, the tritium vials self-illuminate without any battery or external light source, providing a reliable glowing sight picture for defensive and duty use.
How long will the tritium in these sights stay bright, and can they be replaced?
Tritium is a radioactive gas that naturally decays over time. Sig Sauer rates the X-RAY3 tritium vials to maintain effective luminosity for over 12 years under normal use. After this period, the glow will gradually diminish, though the sights remain fully functional as standard iron sights in daylight. Tritium vials are not user-replaceable; when luminosity drops to an unacceptable level, the sights should be replaced entirely.
