Mr. Cunningham.

In other words, the trigger has to be pulled through the whole cycle in a Smith---

Mr. Eisenberg.

In order to disengage---

Mr. Cunningham.

Either that, or cocked before the block will be out of the way. When you pull the trigger and you don't release it or if it is in the cocked position and the trigger is pulled and not released, the hammer will stay forward. The firing pin will stay forward, so you can see it out through the breech face, as long as the trigger is pulled. Then when you release the trigger, the rebound block throws your trigger forward, so the weapon can be fired again.

Mr. Eisenberg.

You are modifying what you had said previously?

Mr. Cunningham.

Yes.

Mr. Eisenberg.

And you do that upon closer examination of the weapon?

Mr. Cunningham.

No; it is On the basis of trying to describe an internal part without seeing it. If you would care to, I can show you what it looks like. I have a photograph of the National Rifle Association breakdown. It would be easier to explain if I could show you what I am referring to.

Mr. Eisenberg.

Could you, please?

Mr. Cunningham.

Yes.

Mr. Eisenberg.

Before you refer to this diagram, could I take a look at it? Congressman Ford, could I have that diagram admitted into evidence?

Representative Ford.

It will be admitted.

Mr. Eisenberg.

That will be 593.
(The document referred to was marked Commission Exhibit No. 593, and received in evidence.)

Representative Ford.

Mr. Eisenberg, do you want the whole article?

Mr. Eisenberg.

I think we might as well put the whole article in, yes.
(To Mr. Cunningham.) Perhaps it would be easiest if you came around here, since the diagram is a small one.
Now, the diagram which you are referring to is on page 61, the second page of this Exhibit.

Mr. Cunningham.

Right.
As you can see, it is a diagram with the sideplate removed. which is this portion right here. It is the right-hand side of the weapon. (Witness pointing to revolver.) We are looking down on it with the sideplate on. These four screws hold on the sideplate.
When you pull the trigger of---

Mr. Eisenberg.

The sideplate is marked 20 over here?

Mr. Cunningham.

Yes--No. 20 is the sideplate.

Mr. Eisenberg.

That is in the diagram.

Mr. Cunningham.

No. 42 in the diagram is the trigger. There is a sear arrangement on the trigger, attached to the trigger. If you cock it, the sear arrangement will go up into a notch on the hammer right there, and hold it back--right in here.

Mr. Eisenberg.

That is number--

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?
