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 revolver. As with all used firearms, thorough cleaning may be necessary to meet your maintenance requirements.

Box, Paperwork, and Accessories: This Diamondback includes its serial matching factory box with styrofoam inlay and various factory paperwork including the manual.

Our Assessment: The Diamondback is essentially a shorter framed Python with a dash of the Detective Special, both in the cylinder and grip frame, sharing similar aesthetic dynamics and is no less striking in appearance than its predecessor. This revolver retains about 97% of its finish with some scattered wear that is most notable on the frame. This will make for a great shooter or will do well to help fill out a collection of Serpent guns. Those familiar with the Python line understand the accuracy these revolvers are capable of; this one should prove to be no different. Good luck and happy bidding!
