Note: The reported serial prefixes are the lowest alphabetically, but production was not always alphabetical. There are situations where a “later” prefix was produced with earlier date codes, thus that gun would technically be the first release. One significant example would be that DN prefix G19 Gen 1s were produced with 4/88 date codes and were made before the AN prefix Gen 1s or the first Gen 2 19s (BM prefix). We’ve chosen to post the lowest letter combination rather than the earliest date code for each model for simplicity.
