Scifi revolver 2.0

A revolver (also called a six shooter or a wheel gun[1][2]) is a repeating handgun that has at least one barrel and uses a revolving cylinder containing multiple chambers (each holding a single cartridge) for firing. Before firing a round, cocking the hammer partially rotates the cylinder, indexing one of the cylinder chambers into alignment with the barrel, allowing the bullet to be fired through the bore. The hammer cocking can be achieved by either the user manually pulling the hammer back (as in single-action), via internal linkage relaying a rearward movement of the trigger (as in double-action), or both (as in double/single-action). By sequentially rotating through each chamber, the revolver allows the user to fire multiple times until having to reload the gun, unlike older single-shot firearms that had to be reloaded after each shot.
