Mr. CUNNINGHAM. You see, this is the sear.
Mr. EISENBERG. Mr. Cunningham, could you use numbers?
Mr. CUNNINGHAM. Yes. No. 39 is the sear, and the sear is attached to
the trigger, which is No. 42 in the diagram.
Mr. EISENBERG. Now, we are referring to the first page of the exhibit.
Mr. CUNNINGHAM. When the trigger is pulled on this particular weapon,
or if the hammer is drawn back, there is a notch on the hammer which
is engaged by the sear. When the hammer is back you have to pull the
trigger to disengage the sear mechanism from the hammer. When you pull
back and it is in the notch, that is known as single-action firing.
Also, No. 30 in the diagram is known as the rebound slide or block,
and this rebound slide is positioned right behind the trigger on an
internal part of the weapon. When the trigger is pulled, the recoil
slide runs in a horizontal direction. As you can see by the larger
drawing right here--it is a small camming action. It comes up, and is
being pushed back.
Mr. EISENBERG. That is in the middle of the second page of the exhibit.
Mr. CUNNINGHAM. Now, do you see the rounded portion of the hammer right
here, right in front of the notch?
