Clearing double feeds

[uspsanewbie]

I took my recently acquired m&p2.0 5" core to a L.E. class and as part of malfunction drills we set up a double feed and then tried to rapidly clear it.  I found my m&p extractor would not snap over a chambered case even when allowed to slide forward from slide stop under spring pressure. 

 

I talked to customer service and they sounded like that is normal,  though my other guns all will.

 

I know doing this is hard on extractors, but is part of emergency malfunction drills and sure beats having to pull out a pocket knife and pry a round out of the chamber. 

Will other m&p 2.0 have the same issue?
