This is a fantastic post and perfect data to support WHY Supica & Nahas have christened these as the “dreaded triple alpha” serial number series.
S&W also did some cutesy garbage by playing with some of the serial prefixes. We all have our own opinions, but I myself believe it was a dumb exercise to debut the 10xx series of pistols with a serial prefix starting with TEN-xxxx, that seems like something a teenager with a Snapchat account would do. On the other hand, the earliest test 3rd Gens with the very rare AIP-serial prefix at least makes some sense, the AIP denoting the “automatic improvement program.”
Either way, deviating from any rational order is simply frustrating for anyone (internal or otherwise) who might ever attempt to use a serial number to possibly identify a period of time.
Yes, it has been said hundreds of times that S&W has been in the business of manufacturing and selling guns, not collectible or heirlooms or minute trivia. I both understand and accept this answer, but it doesn’t change my position that it’s annoying and unhelpful that S&W plays it so fast & loose with serial numbers — specifically since 1980 and the dawn of the dreaded triple alpha serial prefix.
I would add to my argument that S&W opened themselves up to this (esoteric) line of criticism (that they couldn’t care less about

) simply when you consider that they made about one hundred years worth of firearms before they decided to get cute and silly with serial numbers.
You know — in a way, it’s quite fitting. These days, S&W serial numbers are in the same class as S&W’s quality control.
