Difference between a NON-MIM and Factory Extractor?

[smcrea]

Last night I did a REALLY STUPID thing!

I'm replacing my factory installed crappy Remington Extractor on my 870 Express with a NON-MIM Extractor

I placed them both on the bench and then forgot which was which!

I'm about 90% sure that I re-installed the New NON-MIM one..

But can anyone tell me if these is a way of telling them apart?

Thanks!

MY HERO!!!.. THANK YOU!!!

I recognize the remaining extractor that is on my bench as MIM!!!..

I recognize the line across the top of the MIM that isn't on my new NON MIM (top photo!

Thanks again!

Like Vitaly's images showed, the raised gate mark on the outside of the extractor indicates that it's a MIM part.

Also, I'll note that both the MIM and machined (non-MIM) extractors are factory parts. The only aftermarket extractor offered for the 870 is an expensive EDM one from Volquartsen.
