You can't count on it now.
Eagle does a lot of work on Bersas and they do good work from what I am told. When it comes back I bet it will be good and you will be able to count on it, but thats gonna be on you. Some people can NEVER trust a gun that went bad once. Others blindly rust a bad gun because its their favorite brand or it was cheap and thats all they could afford.
I have heard of a few Bersa problems and I have heard Eagle does a great job fixing them. Taking the handles off and eyeballing the inners normally will not tell you whats up.
Good luck with your new little gun. I hope it is 100% when you get it back.
