The cylinder has moderate thinning on all edges along with scattered spots of light surface oxidation. The screw heads are sharp. The markings are clear. Overall, this revolver rates in Very Good-plus condition.

Mechanics: The action functions correctly. The cylinder locks up solidly on each chamber with the trigger depressed. The double action trigger is smooth, the single action is light and crisp. We did not fire this handgun. As with all used firearms, thorough cleaning may be necessary to meet your maintenance requirements.

Box, Paperwork and Accessories: None.

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 88% of its finish with wear consistent with heavy and consistent use. 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 50 years after it was made. Please see our pictures and good luck!
