colt python Building on Colt’s Snake Gun legacy, the legendary double-action revolver returns in stainless steel in 4.25” and 6” barrel lengths. The 2020 Python features modern stainless steel alloys and a re-designed rear sight. Thirty percent more steel beneath the rear adjustable target sight gives you a stronger revolver and more robust shooting experience. A recessed target crown, user-interchangeable front sight, and Walnut grip with the iconic Colt medallion make this a gun you’ll want to shoot AND show off. The Python is chambered in .357 Magnum and also accommodates 38 Special cartridges.
