Picked up a gen 2 G19 several months ago, a police trade in. Late two letter serial number. Recently found another used G19 that is an early three letter serial number, born in 1993. Both have the original, non LCI extractor. The original pistol's grip is almost smooth from being handled, while the newer pistol is in like new condition. New pistol piles brass at 3:30 to 4:00. Perfect. The older deposits brass all over the place from 3:00 to 6:00, though none of it hits the shooter. RSA was changed to no effect. I do not see any real difference in the extractors, despite the obvious higher round count on the older weapon. I trust both to function properly, but am curious if others have noted such a difference on early pistols? There have been so many (righteous) issues with BTF in the last few years that I have started to wonder if there always was a varied ejection pattern on some of the Glocks from earlier days.
