Extractor retention screw

[hugh rather]

Does anyone know the size and thread pitch of the extractor retainer screw on parker doubles?

[Bill Murphy]

Specify extractor or ejector. They are different screws.

[Dean Romig]

I think he means the extractor rod stop screw in the lug.

This is a top lever hammer gun with an extractor.

40 tpi. I'm going with #4, but I can't find my gauge, and a 6-40 won't start.

edit. Chart says Nominal is .112, and the screw I'm holding is .112, so yup, 4-40
