S&W serial number prefix?

[msrtex]

I have a S&W 317 with the serial number prefix DCF and cannot find any information related to 317's having that prefix. Can anyone point me to a reference? I have the Standard Catalog of Smith and Wesson but it shows a different prefix for the 317.

Might have figured it out. I don't see any reference to serial numbers past 2004. Any one know if this is correct?

All S&Ws use a three letter prefix in the serial number after 1983. Started with AAA and was at DCF when your gun was made.

Nothing special or mysterious about it.
