First field strip the pistol to remove the bolt from the reciever
(instructions for that here).
|
Lift up the recoil spring and guide rod up from the bolt
|
|
|
|
You must move the firing pin retention pin to the left (or completely remove it).
This is to allow the plunger that holds the extractor to be pulled back far enough
to remove the extractor.
|
|
Using a small screw driver (I've heard a dental pick works well also) pull the plunger
back away from the extractor. With the pin removed it will be able to travel back
far enough to allow the extractor to be removed. If you hold the plunger back and
turn the bolt the extractor will fall out.

Here you can see the orientation of the firing pin, firing pin retention pin,
extractor and the plunger that holds it in (how they would be together in the bolt).
|

|
|
To install the extractor simply insert the spring and plunger into the bolt from
the front with the flat portion of the plunger facing inside. Then lay the
extractor in the groove and use it to push the plunger back. While pushing
back apply pressure to push the extractor into the bolt, and when the plunger
gets far enough back, the extractor will fall into the bolt, and the plunger
will spring forward to lock it in.

|
Insure the firing pin retention pin is reinstalled into the bolt, and place the
recoil spring and guide rod assembly back in the bolt.
