Thus, as I posted, the confusion. I think what he is talking about is the "extractor star". He may be under the impression that it bears upon the recoil shield. Nevertheless, what he would need are "end-shake" shims...if that is indeed his problem. I would not count on the "extractor star" to be a drop-in fit from another gun anyway.Just call it a "no", practically speaking.
The hand that advances the cylinder rotation isn't a drop-in piece & does nothing for endshake.
