I just bought a Sig P220 and can't find what the proofing marks mean. I figured there were some proofing experts out there that could help me. Please take a look at the pics below and let me know if you have seen any like these. Just trying to understand some of the gun's history.
I also included a shot of some letters that appear above 'Made in Germany.' It's not the serial number because I see that also - does anyone know what these mean? Could they help me date the gun? I think it is from sometime between 1979-1983, but I really don't know.
Thanks in advance!
