*Blued Old Army Serial Numbers rollmarked with Stainless Old Army Revolvers beginning in 1982

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 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, models may be stored for a length of time before they are shipped.

For details on your specific serial number you may contact our Service Departments:

• Pistols: 928-541-8892
