Bingo! I think you got it or, at least, most of it. Extensive analysis of this problem by a number of senior Glock Talk members indicates that: (1) The most recent molded extractors are slightly oversized; and this causes problems with, both, the horizontal and vertical dimensions. (2) The former molded extractor claws are straight when, in fact, they should have a vertical angle to them. (3) The older molded extractor claws do not grab case rims tightly enough; and, consequently, tend to, 'bounce' extracted cases out of the chamber. (4) The inside shoulder of these molded extractors, next to the round, 'pivot post', is too large; and this prevents the extractor claw from grabbing case rims deeply enough.
Glock, GmbH appears to be presently aware of these design flaws; and the necessary improvements are starting to show up in the most recent versions of their new cast extractors; and, yes, polishing the horizontal, 'flats' does help. 'Why'? Because it tends to reduce the extractor's overall thickness and works to prevent binding.
