The firing pin, however, does not move forward to fire the cartridge because the component of force in the direction of the arrow C also simultaneously moves the
"impact" safety bolt 19 into a blocking position in which it engages a recess formed on the lower side of the firing pin. The second safety bolt 19 therefore prevents a movement of the firing pin and an accidental discharge of the pistol due to the impact.
In addition to the action of the
"impact" safety bolt 19, it is desirable to structure the slide, firing pin, and hammer so that the backward movement of the slide following an impact causes the front face 23 of the hammer to strike the edge 24 of the slide and not the rear end 25 of the firing pin.
