Ruger New Model Blackhawk Serial Number History New Model Blackhawk Revolver (Manufactured from 1982 to 1984) Caliber: 357 Maximum Beginning Serial Number: Years of Production: 600- 600- 600- The above chart shows the approximate first serial number shipped for the indicated year. This number should be used as a point of reference only. It is not necessarily the very first serial number shipped, but it can be used to determine the approximate year your Ruger firearm was shipped. Ruger does not necessarily produce firearms in serial number order. There are occasions when blocks of serial numbers have been manufactured out of sequence, sometimes years later. Also, within a model family the same serial number prefix may be used to produce a variety of different models, all in the same block of serial numbers. And in some cases, firearms may be stored for a length of time before they are shipped.

For details on your specific serial number you may contact our Service Department: 336-949-5200 For serial numbers manufactured prior to our electronic records, or for an official letter confirming the details on your firearm please download and mail in the form.

Take the cylinder out and post pictures if you can. Install Flash Operator Panel Asterisk Key. Otherwise look into the cylinder and see where the size necks down. Does it neck after like half way down the hole? Or does it neck down way more towards one end than the other? The first is 45 Auto and the second is 45 Colt.

45 Colt is a much longer round. On the front of the cylinder you will find it's engraved with the same last three numbers as the gun. If it's 45 Caliber it should say right on the left side of the frame below the cylinder '45 Caliber'. I believe the term 'Long Colt' was used to provide a clear distinction from other 45 cal rounds. For example the ACP in 45 ACP stands for Automatic Colt Pistol. The long colt was the standard US military round for many years.
