I purchased a new 4th generation G19 a few weeks ago. I took it to the range and put about 200 rounds of WWB 115gr and 147gr hollow points through it with no failures and just a couple brass landing on my head (which did not bother me a bit). On my 2nd trip to the range I shot: 100 rounds Remington UMC 115gr, 100 rounds of Federal Champion 115gr, and another box of 50 WWB 115gr. Three of the Remington casings hit me in the face, which was a little annoying, but it shot flawlessly (so I decided not to use anymore Remington UMC). On my latest trip to the range I shot 50 rounds of WWB 115gr, and 50 rounds of Winchester NATO 124gr -- I would have shot more but there was too much brass hitting my face (and the brass 2 of the NATO 124gr rounds shot nearly straight back at my right eye and hit the glasses quite hard). About 5% of the shots were launching brass at my head. As you can guess I am not happy with the situation -- I love the way that the G19 shoots and feels in my hand, but brass to the face is not fun. It was test fire was in January 2012. It has the 034 recoil spring and the 30274 ejector. What would people suggest I do at this point to correct the problem?
