I guess I got lucky initially with my Gen 4 because I had only a couple of erratic ejections in the first 100 or so rounds. The gun would eject reliably to the 4 o'clock position. After a few hundred more rounds I installed an Apex extractor and the brass was being ejected strongly to the 4 o'clock to the same exact foot wide circle. Ultimately I don't know if I needed it, but it sure didn't hurt anything.
