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 retains about 97% of its finish with wear consistent with light use. The aftermarket grips are in about Excellent condition but do have some very minor play to the frame and still look great. 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, more than 40 years after it was made.
