So, as some of you probably already know, I got a new extractor for my girl's Gen4 19 that has has erratic ejection issues in the past. I did use the polish the top and bottom of the dipped extractor that came with the gun and noticed much more consistent ejection, but it still didn't seem like "strong" ejection to me. Now, when I fire the gun the ejection is much better so I had my girl fire it (it's her carry gun after all...). When she uses my G17s/G34s/G26 she has stronger ejection with the same ammo vs. what you'll see in the video with this Gen4 19. Here's the new extractor: [ame="http://www.youtube.com/watch?v=TIYtqwcGVA0&feature=channel"]Gen4 Glock 19 Ejection With "Dipped" MIM Extractor - YouTube[/ame] [ame="http://www.youtube.com/watch?v=BSha4adIo3w&feature=channel"]Gen4 Glock 19 With New Non-Dipped OEM Extractor - YouTube[/ame] The same ammo (Blazer 115gr FMJ aluminum cased) was used for all shots. I really didn't notice any difference in ejection but since she fired 200 rounds total of this relatively weak ammo with 0 failures of any kind I really can't complain. FWIW, hotter ammo ejects better.
