I can't seem to find an online resource for S&W serial number dating for my 642-2 PC. The serial number is CYS4295. Can anyone point me to a resource or tell me the DOM? Thanks.
There isn't one.
You either need to purchase the book 'The Standard Catalog of S&W" or pay for a S&W Historical letter. There are serial# tables in the book.
The 3 alpha code S/N's are difficult to pin down, but I do see that prefix being used in 2015. If you have the box, the "Fired Case" is in an envelope with the date of firing written on it. This is about as close as you can come.
Thanks for the feedback. I have the third edition of the SCSW, but it only defines 3 alpha codes through 2004. 2015 sounds about right based on what I know about the gun's history.
