A double/single pistol is described as: the first round is double action, the second and subsequent rounds fire single action as the hammer remains cocked each time the slide cycles.

A double/single pistol is described as: the first round is double action, the second and subsequent rounds fire single action as the hammer remains cocked each time the slide cycles.

• A. The hammer must be cocked manually on every shot
• B. All rounds are single action
• C. All rounds are double action
• D. The first round double action, subsequent rounds single action as the hammer remains cocked

Answer: (D)

In a double-action/single-action pistol, the first trigger pull both cocks the hammer and fires. After the shot, the slide cycles and cocks the hammer for the next shot. Because the hammer is already cocked, the subsequent triggers releases the hammer without re-cocking it, which is the single-action mode. That sequence—first shot double-action, then subsequent shots single-action as the hammer remains cocked after cycling—fits the described behavior. The other options describe scenarios where the hammer is re-cocked manually every time, or where all shots are the same action, which isn’t how this mechanism operates.
