I took my first Glock, a Gen4 G19, to the range this weekend. Approximately 20-25% of the brass hit me in the face. I shot: 100 rounds of PMC, 115 gr FMJ 100 rounds of Blazer Brass, 124 gr FMJ I have never had this problem with my Kahrs, Sigs, XDM or M&P (using the same cheap ammo). I was not limp-wristing. I'm not new to pistol shooting. I have put 1000s of rounds down-range, in the last 6 months, alone. My technique works fine with other brands of firearms. This gun was purchased new this week. I don't see a date of manufacture on box. The LGS who sold me the weapon does high volume, so I suspect this gun was born recently. It is made in USA. I've searched the forum and found others with similar problems. I've noted that technique is often cited as the cause of BTF. To this, I call BS. If you've experienced this problem, and have found a solution, I welcome your feedback.
