Our Assessment: The Diamondback is essentially a shorter framed Python both in the cylinder and grip frame, sharing similar aesthetic dynamics and is no less striking in appearance and mechanics than its predecessor. This revolver is from 1977 with a 4" barrel, chambered for .38 Special. It retains about 95% of its original metal finish, appearing to have seen responsible use over the last 50 years. The 'positive lock' action provides SOLID cylinder lockup, with smooth double and single action trigger pulls. Those familiar with the Python line understand the accuracy these revolvers are capable of, this one should prove to be no different. While most of Colt’s Serpent revolvers are collectible and all appear to be appreciating in value, this could still make for a nice carry revolver today. Please see our pictures and good luck!
