Changes

Unlike many other modern handguns, the Px4 Storm does not use the Browning action. Instead, the Px4 uses the same short-recoil, rotating barrel action as the Beretta 8000 series, and uses the same trigger and safety system as the M9/92/96 series. Despite these mechanical similarities to other Beretta handguns, the Px4 is completely different in terms of design. Light-weight It features a polymer construction frame paired with a steel slide and metal inserts, which was a massive departure for Beretta at the time. The Px4 also sports a rounded trigger guard, which makes it better for concealed carry. A modular trigger group, fully enclosing slide, under-barrel Picatinny rail, and changeable backstrap options for are also highlights of the grip are a radical departure from previous Beretta designshandgun.
