These sights are packaged as front sight only and fit 2020 and newer Current Production Colt Viper, King Cobra and Cobra snub-nose models. These sights do not fit any of the original Colt "D" frame revolvers.
To make fast, accurate shots you need to be able to pick up your front sight quickly and then accurately center it in the rear notch. Firing accurate shots requires you to be able to see the sights quickly and sharply. A number of improvements have been made to our Snake Sights that other sights are lacking. Chief among these improvements are a 14k Gold Bead, brightly polished in a dome shape as well as our Night Sight models with a green tritium lamp surrounded by either a Luminescent Green Ring around the tritium lamp, or a Bright Orange Ring surrounding the lamp.
