Disassembly of Hammer and Safety

1. Field Strip the gun. (Instructions)

2. Remove Trigger. (Instructions) It is not necessary to remove the Trigger, but it does make it easier.

3. Locate between the Grip Frame and the Safety, the end of the Sear Spring (blue circle) resting against the Hammer Pivot Pin (outlined in green).  

4. Move the Sear Spring away from the Pivot Pin (red arrow) and push the Pin out of the Grip (green arrows).

5. The parts in Fig. 2 can now be lifted out or usually fall out. Be careful not to loose the Spring and Plunger in the Safety (blue circle).

Assembly of Hammer and Safety

1. Locate the sear spring on the left side of the grip.

2. With the indent on the pivot pin out (red arrow), start inserting the pivot pin (green arrow) into the left side of the grip.  Make sure the long end of the sear spring is to the right of the pin (blue X).  Leave just enough pin exposed (outline in green) from the grip so that the spring will not be released.

3. Rotate the sear so the top points forward (red arrow).  It needs to be held forward until the safety is in.  Install the safety assembly by placing the safety button into the hole in the grip. Rotate the safety until the hole lines up with the pin. Move the pivot pin in until it is flush with the safety.  Carefully (it can fall off) switch the safety to Fire and release the sear.

4. Assemble the Hammer, Hammer Bushing, and Disconnector as shown below.

5. Align the hammer so that the hole is over the pivot pin.

6. Push the pin until a "Click" is heard or you see the sear spring resting in the notch on the pivot pin.

7. Now that tension is on the sear spring, move the sear pivot pin slightly from side to side to ensure the spring is retaining the sear pivot pin as well.

8. Install Trigger. (Instructions)
