Serial Number - Date Proof - Year of Manufacture - Month/Year of Import - Caliber - Importer - Additional Info (Thanks to Mustang-PaPa for the link and recommendation) If there are dashes, the pistol was produced without such proof marks.Īn excellent resource for background information on various SIG models: If there are two X's instead of the date code, it's because I was never able to confirm what the actual stamp was.

I've done my best to throw out as much junk as possible, while still keeping relevant information - some of which is quite redundant. There are discrepancies here and there in regard to sequential numbering and the associated manufacture/import years, which isn't unheard of, and could be for a variety of reasons not related to misinformation. I've compiled a fairly decent list of serial numbers and their related dates of import and/or manufacture, and hope this helps those who may be looking for such answers/information. Serial number, date code, year, if each is present, then any pertinent information like import markings or a description of the pistol. If you wish to have your gun(s) included please post the information in the format you see it presented in the list, example:

If you have any information to contribute for any SIG models, please post it in this thread.
