Colt Firearms Viper Features The Colt Viper pairs a half lug barrel design with a carbon steel frame to reduce overall weight without sacrificing the durability shooters expect from a Colt revolver. This lighter barrel profile makes the Viper more comfortable to carry for extended periods while still delivering the heft needed for controlled double action shooting. Chambered in .357 Magnum with the ability to also fire .38 Special the Viper gives owners flexibility to practice with milder loads while carrying full power magnum ammunition. The 1:14 twist 6-groove barrel is built to stabilize a wide range of bullet weights across both chamberings. A polished blued finish covers the carbon steel frame delivering a classic Colt aesthetic along with added resistance to corrosion from handling and holster wear. Checkered American walnut grips round out the traditional appearance while giving the shooter a secure confident grip under recoil. The black ramp front sight and integral notch rear sight provide a simple fast sight picture for both deliberate and defensive shooting. With a double action trigger pull between 7 and 9.5 pounds the Colt Viper offers the smooth consistent trigger that double action revolver shooters rely on.
