I don’t know it only has the serial number on the frame. I called Sig about it and was told, they don’t have computer records that go back that far.Is it a German or German frame ? I have a German frame two tone Build Date 02/20/2008.
SA is the prefix for 9mm frames. SA4 is the prefix for the .40/.357 frames. Originally the .40/.357 frames used the SA prefix as well (there were some S4 prefixes also). Then at some point early on SIG switched to the SA4 prefix. As far as I've been able to tell, the SA4 prefixes fall in line with the number on the SA prefixes. So you might have a 9mm batch that ends in SA 95001, then the next batch of .40/.357 frames might start SA4 95002.Was there any kind of change when it went from SA to SA4 in the serial number?
Thanks. That makes sense with the 357/40. Not sure about the sequence though. Your 9mm with SA 098XXX was built a year after mine SA4 110XXX if yours is the correct build date.SA is the prefix for 9mm frames. SA4 is the prefix for the .40/.357 frames.

You occasionally see some serials out of order. The green site has a much larger list--take a peek. It also seems there were times when the frames may have sat on the self at SIG for some time, then SIG "discovered" them, and made complete guns much later than the serial number would indicate.Thanks.

And……The slide serrations are different between the 9mm and 40/357. Quickest way to ID a 9mm.Remember the only difference between the 9mm and .40/.357 frames is the magwell.
Hopefully Willard will know something.,I don’t know it only has the serial number on the frame. I called Sig about it and was told, they don’t have computer records that go back that far.
My German Frame two tone starts SA4 136XXXWas there any kind of change when it went from SA to SA4 in the serial number?
