MP40 Extractor Installation Issue

[J.Ryan.T]

Hello all,

Could someone provide guidance on installing a replacement extractor for an MP40? My original one is worn out and now just sits loose in the bolt groove. I’ve purchased an original German part, but it seems that I need to hammer “not tap” it in forcefully at the pin hole, which doesn’t feel or seem right. Is it common for these extractors to require slight shaving or adjustment to fit properly in the pin hole? Any advice would be appreciated!

First photo is empty bolt next to old and new extractors:

Second photo is the old extractor lying freely in grove:

Third photo is the new extractor laying in grove but will need to be hammered in or filed down to fit.

 Thanks
