G19, Gen 3, S/N TTL***, born on Aug 30, 2012, new style non dip MIM extractor During the first 200 rounds I was getting about 5% back to face. Swapped the extractor, firing pin safety, and spring load bearing assembly from a 2005 G17. We then fired 350 rounds of Win White Box, Blazer aluminum and brass, and Federal Champions (100 of the 350 rounds and the lightest load). I, my wife, and a new shooter that had never shot a handgun before, shot the 19. There were ZERO back to face. During those 350 rounds I started reinstalling the original parts except for the original non dip extractor. Today I reinstalled the original non dip extractor, and back to face started with about 5% of the 100 rounds I fired, mostly with Federal Champions (50 of the rounds fired today). The new non dip extractor does show wear and mold marks. I don't shoot the G17 that much, so I'm just putting that extractor back in to the new G19. Just sharing.
