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. The model was offered in .38 Special as well as .22 Long Rifle, like this one. This revolver retains about 98% of its finish, sporting a bright, sharp bore and solid cylinder lockup. Those familiar with the Python line understand the accuracy these revolvers are capable of, this one should prove to be no different. This will make for a great shooter or a nice addition to a Colt revolver collection. Please see our pictures and good luck!
