Shot about 275 rounds today. Several failure to ejects/stove pipe and crap load of brass flying at my head. I burned the side of my head with when the brass landed between my glasses and my head. I had to laugh but it did hurt. I think I have a bent ejector. The guide rod has a stamp of 042 and the ejector has a stamp of 336. I think I need to call Glock but wanted to see anyone had any other suggestions. Thank You.
