My 4595 is at MOM to address the accuracy, or lack there of. Tech said it sounds like it has a bad barrel. He said they did get a few where the hardening was wrong. Doesn't allow the bullet to fly straight. Possibly shallow rifling. He also said the barrels they get now are the best they've ever had. Regardless, said they would replace what ever was necessary to make it shoot as it should and it will when I get it back. Can't ask for better than that.
