Curious about numbers inside the frame/slide

So I was looking inside the frame and slide of my Loaded model and I notced that each one has a long number (13 digits) engraved on it. The number is different on the slide and frame. Besides being a different number, the frame number begins with an F and ends with an S and the slide number begins and ends with an S.

Those 2 numbers are not the serial number of the gun. As matter of fact they appear to have nothing in common with the serial number.

Just curious but what do these numbers mean? Are they supposed to be the same to show "matching numbers" or something?

Just parts tracking no relation to serial number. Common on Springfields.

My Kimber's have hand the frame # on the inside of the slide. Hand fitting I believe.

Hand fitting kimbers ... ok . But we are talking about different numbers
that are stamped into the frame a slide . Hand fit numbers are usually
the last 3 of the frame serial numbers hand etched into the the parts
fitted into the frame , Barrel , barrel bushing , slide , ejector , barrel
bushing - etc

Pretty much every Smith uses this numbering system .

Thomgetch - Has it right

Probably Parts/Drawing Numbers. If you have access to the IPB (Illustrated Parts Breakdown) manual, that would probably show you those numbers.

If this is true, what a ridiculously expensive non value added way to track parts.

It's 2020....not 1920. Somebody call SA and let them know that barcodes and scanners exist.

It's the way they track their forging/heat treat lots.
