Ok so I bought a new gen 4 model 19 last week. Took it home cleaned it up, and went to the range and put 150-200 rounds through it. At that time I shot all 147 grain lawman and noticed right off the bat the ejection was unpredictable and erratic. The day I purchased the pistol the dealer let me look inside the frame and under the slide. This pistol had the 30274 ejector and the updated recoil spring. After the first outing I was kind of bummed because I wasnt expecting to be having the erratic ejection with the updated parts. Well after doing more research and reading I found out about the "dip" extractors. Sure enough my pistol is equipped with one. I called glock and told them about what was going on, and they said send it in and sent me a call tag. I just wasnt ready to part ways with my new pistol. I read on here that glockparts.com had some of the non dip extractors so I decided to try one before I sent the pistol back. The part showed up today, I installed it and went to the range. I purposely bought several different loads for testing, winchester white box in 115 grain, federal 115 grain, armscor 115 grain, lawman 124 grain, and some winchester nato 124 grain. I figured lets start with the big culprits, the federal and winchester. Everything and I mean everything ejected high and what seemed to be a 45 degree angle towards 4 or 5 o'clock. I couldnt believe it, this was completely the opposite of my first trip. I had casings hitting me in the face, over my head, even to the left of the pistol towards 9 o'clock. This was with all ammos mentioned, I finished the whole box of federal just to see if it may be a fluke, it wasnt. I fired about half of every other ammo listed, all ejected the same but the nato definitely had more pop. The federal had by far the softest recoil, felt very weak. I have had absolutely zero malfunctions still and the erratic ejection appears to be solved. I dont want to make it sound like I have found the cure for all problems or anything special, I am sure I am not the only person with this combination of parts. I just wanted to share my experience with others as there are many unhappy 19 owners out there. I will keep running ammo through the pistol and report back but not as long winded.
