Which action type allows a shooter to fire the first round in double action with subsequent shots in single action mode?

The correct answer is that a double action semiautomatic pistol allows a shooter to fire the first round in double action, with subsequent shots firing in single action mode. In double action mode, the trigger pull performs two functions: it both cocks the hammer and releases it to fire the round. This means that the shooter does not need to manually cock the hammer before the first shot.

Once the first round is fired, the cycling of the slide automatically cocks the hammer for the next shot, allowing it to be fired in single action mode. In single action, the trigger pull only releases the already cocked hammer, requiring much less effort and resulting in a lighter trigger pull. This combination offers a balance between safety and performance, as the first shot requires a longer trigger pull to prevent accidental discharges, while subsequent shots benefit from the lighter trigger pull of single action.

The other options do not meet this definition. A single action only option does not allow for the double action first shot. Double action only revolvers or pistols would require a double action pull for every shot, and striker fire systems do not typically offer the transition from double action to single action as they operate differently. Therefore, the unique feature of a double action semiautom
