Mechanics: The action functions correctly. The cylinder lockup is tight with no movement on all 6 chambers when the trigger is depressed. We did not fire this handgun. As with all used firearms, a thorough cleaning may be necessary to meet your maintenance requirements.

Box, Paperwork & 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 than its predecessor. This revolver retains about 96% of its finish in Fine condition, sporting a bright, sharp bore and minor wear in its rubber grips. 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. It’s in high enough condition that it will interest collectors, but shows just enough wear that you can take it out to the range instead of keeping it as a safe queen. Please see our pictures and good luck!
