Make sure you got the proper extractor. check whether you need the 15 degree or 90 degree one.I have a gen. 2 G19. I ordered a new extractor. The new one will not work. The best way to describe it. The part i got new is thinner where the firing pin safety touches it. Or other way is the new one is receased on both sides. The original one is the same thickness on both sides. Sorry about no pictures. But i could not get them to show this detail.
