Pictures of the original and aftermarket extractors show the aftermarket one is slightly different in several dimensions.

The learning for me is, never assume anything not proved by actual test, beware aftermarket parts, and test any replacement part at the range promptly. I'd forgotten I had changed the part and assumed that changing a small part would not impact function so had not bothered to test.

I'm offering this story to help anyone who has a toggle that doesn't quite close, and to illustrate the diagnostic process that (eventually!) worked. It is also a cautionary story about how fairly minor changes in part geometry can have a a noticeable impact on function. The matter reminded me that the Parabellum when properly set up and adjusted is a robust and reliable pistol, but the set-up is not trivial.
