I have several, but cannot look at them at the moment.
Honestly - I'd wait and see what happens after more rounds.
It wouldn't hurt to contact Beretta and email them the photos, I suppose. But, I'd just keep an eye on it and see what happens. It is a machine. Different things happen during the manufacturing process on different guns. If it shoots fine, never changes, and doesn't malfunction - I personally wouldn't worry about it. If it gets worse, then it is worth looking into further.
