Beretta PX4 Storm Review:The Beretta Px4 Storm is a semi-automatic pistol designed for concealed carry and personal defense. Its mechanical operation is nearly identical to the Beretta 92 pistol and Beretta M9 pistol, yet it shares very little in terms of aesthetics.The Beretta Px4 Storm contains features common in concealed carry pistols without sacrificing the reliability of Beretta’s proven design. Each Px4 Storm features concealed carry friendly options such as a rounded trigger guard, a take down bar instead of the takedown pin featured on the Beretta 92, and a lightweight polymer body. A three dot sight system performs well in low light self defense situations. The entire pistol can be field stripped and cleaned without tools, and due to design, cannot be reassembled incorrectly. Like most other Beretta pistols, the magazine release button can be configured for left handed operation.The Px4 Storm is available in sub compact, compact, and full frame sizes in both 9mm Luger (9x19 Parabellum). There is also a full frame model of the Px4 Storm available in .45 ACP.
