Heckler & Koch factory records
Who holds this maker's production records today, whether a serial table exists at all, and what it costs to have the archive read them.
HK pistols date themselves if you know where to look, and the code is not in the serial number. The two-letter date code is stamped separately on the left side of the slide, beneath the serial. That is why HK serial prefixes cannot be turned into years the way Ruger's can, and why community tables of HK serial prefixes are so unreliable. HK answers dating enquiries directly.

Can a serial number date a Heckler & Koch?
From the serial number alone, generally no — and that is the honest answer rather than a gap in this site. There is no published table to compare the number against, so any year you find online for this maker comes from a secondary reconstruction, and those are exactly as reliable as their author.
Dating then rests on what is on the gun: the maker's marking and address, the model and its catalogued period, proof marks and their era, patent dates, and the manufacturer's own model history.
Date a firearm by its serial number
