@bentbiker: thanks a lot, now i know what "dip" means and refers to. does the older NON-dip extractor perform better than the newer "dipped exctractor"? where all the NON dip extractors also always NON LCI extractors, or can there be dipped NON LCI extractors also? @ken: got my NON-LCI extractors directly from glock, ordered especially NON-LCI ones, otherwise they would have shipped me the newer LCI-ones! complete with spring plunger and bearing, changed that all, i also installed s .40 ejector , those parts solved the prob.
