The Colt Viper is designed for concealed carry use and features a half-lug design for better concealment and reduced weight. The stainless steel frame allows for improved durability and corrosion resistance while also improving the shooting experience by helping to absorb felt recoil.

This model is chambered in .357 Magnum and features a 4.25-inch barrel and a six-shot capacity. It is compatible with .38 Special ammunition without any additional modifications.
