[FONT=Arial, Helvetica, sans-serif] I purchased a new Glock G19 Gen 4 the last week of September. I own five Gen 3 Glocks (G17, G20, G27, G30, G32) and have never experienced a problem with them. They work perfect every time. This new Gen 4, I have, has had nothing but problems. My gen 3 glocks, it does not matter, I can shoot it weak handed, two handed, strong handed, and they perform flawlessly with ANY ammo I put through them. My Gen 4 G19 must be a lemon. I have "shot" 950-1000 rounds through it and it will malfunction at least once per 15 rd magazine. It jams, stove pipes, Failure to feed, on average 1 in 10 to 1 in 15 rds. When it does not jam, it throws the casings erratically. It mainly throws the shell casing directly in my face. On occasion, when it doesn't throw it directly in my face, it will shoot it out to the LEFT, or IN front of the barrel. It very rarely will throw it to the right, like it should. Yesterday, I contacted Glock and they said they are working on new "weaker" revised recoil spring assembly, but it will not be available until at least Mid to late November. (see update at bottom of page) I have tried several types of ammo. I have used WWB, Federal, Monarch, Blazer AL, Black Hills, Corbon, Winchester NATO, Fiocchi and Speer. I have tried the hotter loads of +p and the NATO, but I still experience the same problems with all the different ammo, and will all three magazines. Mainly now, with the hotter ammo, it doesn't FTE as often, but it will throw it right back in my face/eyes. I cant remember if I mentioned in this post if I changed out the ejector, but I did, and it had no effect with it throwing the casing in my face. I have read on here where the spring is too strong so I have spent several nights "racking" the slide back and forth. I have done this over 2000 times. I even tried GlockWorx aftermarket tungsten guide rod with adapter, and their blue and red recoil springs. I tried their ejector because they said it would throw the casing to the right. But it still throws it back in my face, and it still jams. I even tried gen 3 guide rod and spring from my G32 with the adapter and it still malfunctions. I tried new gen 4 revised "02" recoil spring for the G17 and it just stuck out about a 1/4" in the front. It would still jams with that. The only way I could get it to NOT jam was to use a Gen 3 G17 poly guide rod and G17 gen 3 recoil spring. It did not jam with the G17 Gen 3 spring and rod, but it still ejects the shell casing into my face. Here is a link to a youtube video of the slow motion shell ejections and I think this is what mine is doing. Start watching at 2-1/2 mins for the ejecting problems. http://www.youtube.com/watch?v=wkHEdNx0Mk4 Attached are some photos of my actual jams. I literally have hundreds of photos of it jamming, but these are just a few. Notice on the last photo, the shell casing is flipped 180 degrees. [/FONT] GOOD NEWS. I called glock back today because I was going to send my pistol back and Fred said you wont believe what I got today. He said he just received the prototype (see post #34) in for the Gen 4 G19. So he shipped me out one today. I should receive it about Monday or so. Hopefully it will fix my problems I have been having. I am keeping my fingers crossed. Ill keep yall updated.
