Seems like it's not a recent thing. I have a book called ""The Complete Glock Reference Guide" 3rd Edition published in 2006. On page 36 of this book, they have a section on "Ejected Brass". Let me quote the whole section... "Wearing a hat or shooting glasses will help to protect your face and eyes from the occasional piece of ejected brass. Many shooters experience ejecting brass hitting them in the face. You can fix this problem by simply changing ammunition brands or bullet weights within a brand. The power factor difference between each brand and bullet weight will effect the distance and angle of the ejected brass. Keep switching manufacturers and bullet weights until the ejected brass simply misses your head. But what if you do not want to change the ammo you are using? The fix to this problem is to change the length and angle of your ejector. You cannot start the ejection process sooner, that would require a longer ejector. You will have to delay the ejection process. Remove the trigger housing and stone or file the ejector a little at a time. Change the length and angle of the ejector until you get the desired effect (ejected brass misses your head)." So...this book is the 3rd Edition with a 2006 printing date. I don't know when the first edition was, but I suspect the same advice was in it. This was LONG BEFORE the 4th Gen Glocks came out. And people were still experiencing brass hitting them in the face. So it's not a new thing. The fix seems simple enough. I would buy a spare ejector and go to work on it. That way you would still have the original in case you goof up. This will also sort out the replace guys from the real gunsmith guys. Or you can do as I suggested previously and take it to a competent gunsmith. Of course, if you prefer to piss and moan on Glock Talk, you can continue to do that too.
