S&W lists the M&P as double action only. My question concerns the striker firing mechanism. In a traditional DAO firing system the first trigger pull acutates the hammer, releases it to fire and the hammer is home when the slide returns to battery with a fresh round stripped from the magazine in the chamber. In the striker fire system the striker is cocked when the slide is cycled rearward and returned to battery correct? So, on the first trigger pull, the trigger is simply releasing the striker fired firing pin? Wouldnt this be more correctly described as light hammerless single action only if this is the case?
