today was my 3rd hour long session with my gen4 g19 and i shot 405 rounds of speer lawman 124gr. today was the first time with the glock .40sw extractor, and not a single erratic ejection throughout the entire hour. the previous 1st and 2nd hour long sessions with the g19 oem extractor caused erratic ejections about half hour into each session, but today it was all flawless. thanks to voyager4520 for mentioning the .40 extractor in several previous threads, otherwise i probably would've never picked up on it.
if the polishing doesn't work for you as it didn't for me, try the .40 extractor.
