It is an extension of the older 2 digit model numbers that have been in place for ever half a centuryMy father-in-law got one of these. When I saw the "327" I assumed that was the caliber. But it is a .327 mag. revolver. That's confusing. Why would S&W use "327" as a model number knowing it is also a caliber?
Well, it's still confusing! The Model 29 for instance. Subsequent improvements added a dash number Like 29-2. Glad S&W didn't add "44" before "29".
