Frequently Asked Questions
What makes Optic Yellow better than white for low-light shooting?
Optic Yellow is primarily based on the white light spectrum and is highly reflective, which means it charges the photoluminescent properties of the dot faster and more intensely than standard white or green options. In transitional lighting — such as dusk, dawn, or indoor environments — the Optic Yellow dot glows brightly before it's dark enough to require the tritium insert, giving you continuous visibility across a wider range of conditions.
Will these sights fit my specific Sig P320 or Springfield XD variant?
XS Sights designs these DXT2 Big Dot sights to fit standard Sig Sauer P226 and P320 models as well as the Springfield XD series. However, fit can vary by sub-model (e.g., P320 Compact vs. Full-Size) or generation. It's always recommended to verify your exact model's sight dovetail dimensions with XS Sights' compatibility chart or contact Goodland Guns for confirmation before purchasing.
How long does the tritium in these sights last?
Tritium is a radioactive gas that naturally diminishes over time. XS Sights' tritium vials have a half-life of approximately 12 years, meaning you can expect strong self-luminous performance for roughly 10–12 years under normal use. After that point, the photoluminescent glow dot will continue to function indefinitely with ambient light charging, though the tritium brightness will gradually reduce.
