The Vertec has vertical grips, the aforementioned accessory rail, but no one has mentioned the dovetailed front sight, and the higher rear sights. It should be very easy to swap in tritium nightsights on the Vertec.
I have small hands and never much cared for the feel of the standard 92/96 series. The changes in the Vertec make for a much better balance for my hands. Those who prefer the original 92 don't care much for the Vertec, but those who didn't like Berettas before should try handling the Vertec.
