Just picked this up on Monday. I ordered it almost exactly 3 months ago from my local LE S&W dealer here in IL. SKU# on this model is: 12661
Production date was two weeks ago. May have been one of the first of the new LE pistols shipped since they were announced @ Shot show in January. First one I've seen other than posted on FB & IG by Brandon Wright who is a LE rep for S&W and a member of team S&W.
The new LE market pistols no longer have "CORE" or the CORE logo engraved on the slide. They are no longer listed as "CORE" pistols either. The LE guns are now "Optics Ready".
The CORE option cut out has been revised and is approximately .050" longer than that on my 2019 4.25" LE CORE. The factory spacer plates are now made of plastic instead of metal. Thankfully C&H Precision has already made a new "V2" plate for the 2020 CORE pistols:

Also new is the additional forward slide serrations, and a new more pronounced slide stop lever.
I had all of the following additions on-hand and ready to install as soon as the gun arrived:
Trijicon SRO (2.5MOA)
C&H Precision RMR/SRO CORE plate
APEX Poly/Curved Duty Carry Trigger Kit
HYVE extended magazine release
