Picked up a M9 recently that I bought from that at the FFL.
Noticed two weird things.
1. There is spotting on the barrel
2. And there is no serial # on the box it came with. I have never heard of a firearm manufacturer not putting a serial number on a box.
Do I need to be concerned?
Gun was sold NEW
1. No idea about that....
2. Those boxes came with an cardboard outer sleeve new that had the firearm info on it....this makes me think the outer sleeve was damaged, maybe by water which would explain #1
He DOES have a 2018 Beretta according to the Beretta Firearm Technical Data Search Form (LE model to boot)the barre rust flecks makes it look like a beretta that was forgotten for 10+ years in the store then sold when they found it in the water leak corner with the boxes junk they can't sell, that's if it's new

It's probably just a poor finish on the barrel.
