After dealing with semi-poor extraction with my Gen 4 G19 and an ocasional FTE (1 in about ~150 rounds), I was finally able to install the Apex Glock Extractor (FRE). So far so good.. ~250 trouble free rounds. I read a lot about the ejection issues appearing in Gen 4 Glocks after some number of rounds (often referred to as a break in period). My personal G19 ran flawlessly until the 800-1000 round mark, where it began wimpy ejection and even FTEs. Here is my question - can I expect a similar "break in period" with the new Apex extractor? In other words, am I in the clear?
