Sig Xray Pistol Sight #6 Front & Rear Square - Enhanced Accuracy & Visibility

The Sig Sauer X-Ray3 pistol sight #6 front and rear square delivers the kind of low-light performance that changes how you train and carry. Built around a tritium 3-dot system, these sights glow reliably in darkness without sacrificing daylight visibility—no more swapping setups between night and day. The high-contrast design (blacked-out rear, bright front dot) cuts through target acquisition time whether you're on a low-light range or working in variable conditions.

What makes the X-Ray3 stand out is the marriage of night-capable tritium with a large, chemical-resistant fluorescent polymer front dot. That front element stays bright and visible in daylight while the tritium backing ensures you're never left blind when the sun goes down. The steel housing wraps both sights in real protection—not just from recoil and impact, but from cleaning solvents and the elements that degrade lesser sight systems over time.

These are purpose-built for shooters who demand consistency across all light conditions without fidgeting with their setup. Whether you carry for work, sport, or self-defense, the X-Ray3 stays at peak performance. The tritium has a 12-year half-life, and the sights themselves have been torture-tested to 20,000 rounds—a design pedigree that shows. The #6 square rear fits a range of modern Sig platforms, making this an upgrade path for thousands of working pistols.
