I have a Shield Plus 9mm which had some discoloration on the extractor.  I decided to swap it out.

My extractor assembly was just the extractor, roll pin, and red spring.  Now it appears there is supposed to be a linear spring and plunger as well which sit inside a groove on the extractor?

Is this something only found on the 40 and 45 versions or is my gun missing these parts?  It's never been disassembled so if they are missing, they weren't included by the factory.

Yes, it is supposed to have the spring.
I am an LE armorer, and we have about 30 dept-owned 9mm shield plus guns.
I swapped extractors on them last year and every single one had the linear spring inside.

Interesting.  I have some ordered.  I’ll also keep a couple in the spare parts box.  Odd that S&W would leave them out.
