There is only cosmetic difference between the
M9 and the 92FS.
The M9 has a matte finish that feels like a cheap paint and will scratch off much easier, where the blued 92FS or the stainless look and feel much higher quality. I would say its a big difference.
In my opinion, the M9 should be far less in price than any other 92 pistol because of the poor quality of the finish.
Hate to tell you but they both have the same finish.
I was watching them finishing both models at the Beretta factory in Accokeek, Maryland.
The decision was made to simplify production. Anything that the Military wanted also went on the commercial product.
