I bought a Glock 23 and shot it for the first time the other day and noticed that all of the brass came out slightly dented at the rim. I have read posts that say nothing to worry about, but I thought I would run it up the flag pole. Here is a pic, sorry abt quality, it is a cell pic. I think it is where the brass is hot coming out and when it hits the ramp, it is folding it. I was using Federal 180g FN bullets. No failures to eject.
