When did the extractor with the LCI appear?

I'm looking at a used Gen 3 21, but it has the smooth extractor rather than the one with the LCI. Just curious about when the transition took place. I had one several years ago in this configuration that was an awesome shooter with nary a problem, so I assume this one would follow suit. I think I can grab it for about $385. Other than a good cleaning, would it be worth upgrading the extractor, or should I just leave well enough alone?

LCI introduction: about Dec 1989 per the Serial Number Project.

GLOCK, INC. Technical Bulletin #920403

April 1, 1992
Glock, Inc. announces a production change of the firing pin safety system. This new firing pin safety system has been installed in all production Glock pistols since November, 1991. A voluntary upgrade is being offered to maintain the Glock tradition of ensuring that all of our pistols are up to the latest standards in 21st century Glock technology.

Most importantly, the components of the new firing pin safety system are not interchangeable with the components of the old system and Glock will always strive towards maintaining this feature of interchangeability while working to ensure future interchangeability.

The upgraded firing pin safety system consists of: the firing pin, firing pin safety, the extractor, the spring loaded bearing and the trigger bar. The upgraded system is applicable only to Glock pistols with the following serial number ranges:

Glock 17 - alpha prefix AA - WF
Glock 21 - alpha prefixes through XL
Glock 19 - alpha prefixes through WJ Glock 22 - alpha prefixes through YA
Glock 20 - alpha prefixes though WW Glock 23 - alpha prefixes through SK

The upgraded firing pin safety has a new surface finish making it nearly 100% saltwater corrosion resistant. Also, after rigorous and extensive testing, the new system proves to be more durable and has a longer useful life. Here, as always, Glock is working toward maintaining its standard of perfection.

If you have any questions or concerns please call Glock, Inc. Customer Service
