I was at my local dealer and noticed the new (to me) beretta px4 storm. I handled it and it felt very good in the hands, very slick and seemed to have a good sa trigger. The only thing is that I'm really interested in the rotating barrel. This just seems so out there to me. Does anyone have any experience with this particular pistol, whether 9mm, .40, or .45? Any experience good or bad is helpful. As always thanks guys.
