OPERATIONAL FEATURES NOTICE: The numbers in the figures refer to the photos on pages 53 and 54. Semiautomatic firing. Px4 Storm Beretta pistols will automatically reload after each round is fired, as long as there are cartridges in the magazine. Rotating barrel (Fig. 1-2/E). The Px4 Storm pistol uses a durable rotating barrel locking system. The locking lugs increase accuracy when firing. Reduced friction areas between the barrel, slide and central block, guarantee smoothness of operation and great reliability in all conditions. In addition, the enlarged outer barrel muzzle diameter ensures a precise and constant barrel-toslide coupling enhancing the accuracy of the pistol. Low barrel axis position. Thanks to the design of the direct barrel-slide locking system, the low barrel axis reduces felt recoil and minimizes muzzle rise. Single/double action (models F and G). The F and G versions fire double action on the first round (the pull on the trigger in the double action mode will first cock the hammer completely and then release it to strike the firing pin) and single action on the following rounds (as the hammer stays in the cocked position after the first round). The first round can be fired also in single action mode if the hammer is manually cocked prior to pulling the trigger. The short and light single action trigger pull allows for faster, more accurate discharge of subsequent rounds. The long and heavy double action trigger pull is considered a safety feature because it also helps reduce the likelihood of unintentional discharge. The hammer has three different positions: Decocked hammer (Fig. 5-6): The hammer is in the fully lowered position. The pull on the trigger in the double action mode will first cock the hammer completely and then release it to strike the firing pin (double action). Hammer in the half-cocked position (Fig. 7): By pulling the hammer rearward for a few millimeters its half-cock notch will be caught on the sear. You will feel and hear the hammer "click" into 57
