Call Johnny Glock and talk to him about what you want your trigger to feel like. He will let you know if he can build it or not. Great guy to deal with and builds a great trigger too. Good luck!
I would try some good factory ammo first before I would get too upset. Get a couple of hundred rounds and see what happens. Make sure it is well lubed. If it is still not running well, take a short video and send that to ZEV. Good luck!
Call Johnny and talk to him. He is very knowledgeable and easy to talk to. There was no rush and no pressure. He has my G34 right now doing some work on it. I personally like shooting with a wall instead of a rolling break. Just my preference.
