The room this works is that the discharge of the round causes recoil which pushes the skid back, ejects the spend case and chambers a modern round. At the like time though, this bounce is resetting the malleus and arming it for the adjacent shoot, so the shooter does not have to cock the hammer manually or revert back to double-action trip pulls again. This allows all shots from the 2nd forth to be shorter and lighter single-action pulls .
