The XS Sights Standard Dot tritium revolver night sight for Colt Viper brings low-light visibility to one of the most reliable defensive revolvers in production. If you carry or shoot a Viper and have struggled to acquire your sights in dim conditions—whether at the range at dusk or in genuine defensive scenarios—a quality tritium front sight is a straightforward upgrade that works. This is a serious alternative to factory brass sights, built to deliver a usable sight picture when ambient light fails.
The dual-illumination design handles the full spectrum of shooting conditions. In bright daylight, the high-contrast orange dot provides sharp, fast target acquisition. When light drops, self-luminous tritium takes over, glowing without batteries or activation. The photoluminescent glow dot absorbs available ambient light and adds another layer of visibility in transitional and low-light environments. That combination means you're not hunting for your front sight whether you're shooting at noon or navigating a nighttime scenario.
XS Sights machines these from durable steel and backs the tritium with a 12-year warranty. Installation is straightforward—the kit includes a hex wrench, blue threadlocker, and detailed instructions for the front sight set screw. Whether you're upgrading a defensive Viper, a range gun, or a hunting revolver, a purpose-built tritium sight is one of the few modifications that genuinely improves real-world performance.
