Tried again this weekend with same result. I called Glock directly and they are shipping me a new recoil spring. They are aware of the issues with the Gen 4 Glock 17 and 115 gr ammo. I put 130 something grain through it and it was better, but jammed on the 4th round.
Some people had the original spring completely come apart on them while firing. eeek.
So, we will see what happens when I get the new spring!
