And for what it's worth, I had my first BTF with my G20SF during my last range session which was right around the 1000 round mark for this pistol. More testing is in order, but I am hoping this is an anomaly.
I agree with Raleigh Glocker in that Glock should be (again) made aware this issue still exists with their guns. The videos I believe are helpful. Though I think Arc Angel may be right, in that it may take a large police or military contract to threaten to scrap their Glocks before the upper management at Glock takes a serious look at the issue.
