Which statement best describes the revolver's cylinder operation?

• A. It rotates to align each chamber with the barrel and firing pin
• B. It remains fixed during firing
• C. It ejects spent cartridges automatically
• D. It anchors the hammer

Answer: (C)

During firing, the revolver cycles by rotating the cylinder so a fresh chamber lines up with the barrel and firing pin. The cylinder must turn to present each cartridge in turn; it does not stay fixed during firing. How it turns depends on the model: in double-action, a single trigger pull cocks the hammer and rotates the cylinder; in single-action, you manually cock the hammer to rotate it. Spent cases aren’t ejected automatically by firing—they’re expelled when the cylinder is opened and the ejector rod pushes them out. The hammer is operated separately and isn’t anchored by the cylinder. So the key idea is that the cylinder rotates to align each chamber with the barrel and firing pin.
