While reading up on the Gen 4 BTF / erratic ejection problems, I found forum posts (not all on this forum) by Randy Lee of Apex, and others, claiming that the ejection port is at least part of the issue, and that the gun would eject better if the port was lowered, like on most 1911s. However, I have not read tons of posts with pictures of lowered Glock ejection ports. In fact, most of the very little info I turn up when searching, involves lowering the port when adding a red dot mount. So why have more people not done this? If you personally have had ejection issues that you couldn't fix by swapping parts, why have you not lowered your ejection port? Wanna kill these ads? We can help!
