Just learned that my May 2012 G23 Gen 3, S/N TCX2xx has an extractor with the dip. It was very hard for me to find photos of what I should be looking for. Anyway, here are the photos from m4carbine.net Replacements are on the way from midwayusa.com EDIT: I'm not sure Midway has the new non-dipped extractors for .40 Glocks. All the posts I've seen referring to the new non-dipped design have referenced 9mm extractors. http://m4carbine.net/showpost.php?p=1323727&postcount=816 Wanna kill these ads? We can help!
