As mentioned in previous posts, many current production Glocks suffer from extraction/ejection issues. Some of my recent production Glocks have been great right out of the box (such as my FDE Gen 4 Glock 19). Unfortunately, my brand new Gen 4 Glock 34 had an ejection pattern that looked like a lawn sprinkler. Thanks to Apex Tactical Specialties, this is no longer the case. If you have an extraction/ejection issue with your Glock, check out Apex Tactical’s Failure Resistant Extractor.
