A few Beretta 92 questions

[Rmiked]

Reading various posts I have a few questions: ( forgive me as I am rookie but becoming cult-like Beretta fan)
1. How is a Vertec slide different than non-Vertec? Is it the dovetailed front sight?
2. What is a Pizza gun?
3. Do any models besides Elite have front slide cocking serrations? That is a nice feature. Understand the Langdon 92 will have that.
4. On the Langdon 92, will it be a SS finish barrel with otherwise black finish? (2 tone)

1: yes, dovetail front sight, other than that, it's almost identical afaik

2: reference to the fact that Beretta is in Italy, hence pizza, hence nickname

3: not as far as I know. I've got almost everything but an Elite model and none have front cocking grooves

4: sorry, I'm not sure.

Thanks for info. Regarding Langdon 92, he posted it was Bruniton finish except for barrel. Sounds 2 tone to me but no one has called it that as far as I can tell

From my understanding it will be a stainless barrel and a black slide/frame. Slide will have front cocking serrations and dovetailed sights.
