Frequently Asked Questions
Will these X-RAY3 sights fit both the P938 and P320?
Yes. This specific X-RAY3 set is designed to fit the Sig Sauer P938 and P320 with a square-notch rear sight configuration. Always verify your pistol's existing sight cut dimensions before installation, and consult a qualified gunsmith if you are unsure about compatibility with your particular P320 variant or grip module.
How do the X-RAY3 sights perform in full daylight versus low-light conditions?
The X-RAY3 system is engineered for both environments. In low-light and darkness, the tritium inserts emit a self-luminous green glow that requires no batteries or activation. In daylight, the tritium lamps are surrounded by a bright white ring that maintains a high-contrast sight picture without relying on illumination. This dual-mode performance means you never need to swap sights between daytime and nighttime use.
Do these night sights require any special maintenance or replacement?
No special maintenance is required. The tritium inserts are sealed within steel housings that protect them from recoil forces, cleaning solvents, and environmental exposure. Tritium is a naturally decaying isotope, so brightness gradually diminishes over time — Sig Sauer's X-RAY3 sights are rated for over 12 years of reliable illumination before any noticeable reduction in low-light performance. No batteries, charging, or periodic service is needed during that lifespan.
