Same opinion here, if it comes back fixed or new I'd test it out again. There was something about the gun that drew you to it in the first place and you're already getting used to it. I've felt the Stoeger Cougar in 9mm and loved the ergonomics and that rotating action was interesting. I've had to replace a broken firing pin spring one of my carry guns and I still trust it. That was on a Smith and Wesson revolver.
The gun still shot but I happened to notice it.
I have a friend who says he trusts refurbished items sometimes more than new because the weakest link has been identified and replaced.
Enjoy the gun and have fun testing it!
