Is there any difference between the 9mm and .40/.357 slides? Other than the calibre markings of course. Are the extractors and extractor sockets the same in 9mm and .40 slides? I was thinking maybe the new extractor I got was for .40 calibre Steyr that’s why it’s not flash with the slide? Can anyone who owns both 9mm and .40 or .357 pistols post a picture of the ejection window of two slides next to each other?
