I just picked up a new "wish book", yesterday. (The Complete Book of Guns-2007 Buyers Guide, Harris Pubs.) The Beretta 92 is not listed. They list the 90-Two, and a "90" and under the "90" they mention the M9A1. I wonder if the designation was changed to "90" to avoid confusion with the "90-Two". There are other details listed, but I'm not all that familiar with the minute details of the models.
