The Sig Sauer X-Ray family of handgun sight upgrades is designed to enhance intuitive and quick target acquisition across various lighting conditions. The X-Ray1 model features a front sight that integrates a durable fiber-optic light pipe with a photoluminescent ring, providing a bright dot in daylight and a glowing ring that remains visible during dusk transitions. These 3-dot sights excel in low-light environments, especially when paired with a weapon-mounted light, ensuring optimal performance in critical situations. Constructed with rugged steel housings, the X-Ray family of pistol sights guarantees reliability and durability, ensuring that your sights will last as long as your firearm. Upgrade your handgun with the X-Ray sights for improved accuracy and confidence in any shooting scenario.
