Simple question: Is the ejection pattern from your 9mm Glock consistent and not to the face? Or is it inconsistent, haphazard, unpredictable? Some people claim to have never experienced the BTF (Brass To Face) phenomenon. But BTF is only a part of the larger question of whether or not your 9mm Glock's ejection pattern is consistent. If functioning properly, there should be some consistency to the ejection pattern. Just saying that you've never experienced BTF is not the same as saying you have a consistent ejection pattern. So, just tell us whether it is consistent and not to the face.
