Colt Mfg Viper Viper-Sp3Wrr 357 3 Ss
The Colt Viper is a compact 357 Magnum revolver built for shooters who need reliable defense or ranch carry in a lightweight, concealable package. Chambered in 357 Magnum and fully compatible with 38 Special, this stainless-steel wheelgun pairs classic Colt engineering with practical field features that work as hard as you do.
At just 26.9 ounces with an 8-inch overall length, the Viper's half-lug barrel design cuts weight without sacrificing the power and accuracy that make 357 Magnum popular across hunting, sport shooting, and personal defense. The forged stainless-steel construction handles hard use and elements, while the recessed target crown ensures consistent shot placement. A six-round capacity covers most defensive and hunting scenarios, and the traditional American Walnut checkered grips provide reliable control in any weather.
Sights are straightforward and functional: a black ramp front sight pairs with a U-Notch rear for quick target acquisition in low light or fast sequences. The revolver operates in both single-action and double-action modes, giving you speed when you need it and precision when you want it. Double-action trigger pull runs 7 to 9.5 pounds—within the range most wheelgun shooters expect—while single-action engagement delivers the crisp break many prefer for distance work.
This is a revolver built to work: Colt's 357 Magnum reputation, practical dimensions, and honest sights make the Viper equally at home on the nightstand, in a truck holster, or on your hip during a backcountry hunt.
