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 96% of its finish with light wear in the grips, sporting a bright, sharp bore and solid cylinder lockup. This will make for as beautiful a display piece as it would a shooter. Those familiar with the Python line understand the accuracy these revolvers are capable of, this one should prove to be no different. Please see our pictures and good luck!
