I am a new member who purchased a new gen 4 17 yesterday. I was planning on getting to the range this sat. but could not wait, so ran over there this afternoon after supper. I put five full mags of 115 blazer brass through it without a single problem. Before I made the purchase I had been reading some of the posts here on glock talk about ejection issues with some gen 4's (BTTF). I took note today of how the spent rounds ejected. All were over my right shoulder at about 4 o'clock and 2 ft from my right foot on the ground, except for one that landed on my right shoulder. This seems to be a fairly new production gun. The test fire date on the envelope with test round is 7/12/12. Ser # start with "T" Is this normal ejection for this gun. I have a LC9 that ejects about six to seven feet to my right at 3 o'clock. Thanks for any input.
