I went to the one in Fort Worth. They had the 90-two, 92FS, Px4 and a Cx4. They let me shoot each one. After shooting the 92FS, they let me shoot the 90-two again so I can feel the difference. It did feel a little bit tamer. I liked the Cx4 better though. Maybe because I'm used to polymer frames. Dunno.
I don't think I'd buy one at regular price. I would if it was a steal of a deal.
