Beretta BU9 Nano Beretta BU Nano User Manual - Page 26

GENERAL OPERATION The Beretta Nano pistol is a semiautomatic firearm using a cam operated, tilt-barrel, locking system. When the pistol is fired, the recoil energy causes the barrel and slide assembly to move to the rear. After a short distance, the barrel is forced down and is stopped by the operation of the barrel cam and disconnect pin interface. The slide continues its rearward travel under inertia, extracting the fired case from the barrel and ejecting it through the ejection port. The recoil spring pushes the slide forward, feeding the next cartridge from the magazine into the barrel chamber. Continued forward movement causes the barrel cam to raise the barrel into its locked position in the slide and engage the striker with the cocking lever. The slide is designed to remain open after the last cartridge has been fired and the spent shell casing ejected. LOAD CHECK WARNING: Keep your finger OFF OF THE TRIGGER and the barrel pointed in a SAFE direction when checking to be certain your Nano pistol is unloaded. To visually check to be certain your pistol is unloaded carefully follow the steps below. Remove the magazine by depressing the magazine release button. Retract the slide and visually inspect the cartridge chamber. The pistol is unloaded when no cartridge is visible when looking into the open chamber. 26
