You must be referring to the 9000S, Beretta's new pistol with the "fiberglass reinforced technopolymer frame", yes?
I'm wondering if the 10-round M96 mags will fit as is (no spacers or adapters). I have 6 of these for my Border Marshal 96, and am considering a 9000S as a smaller, lighter CCW. Sharing mags would be a real plus.
