There is not much to it.
As always, make sure the pistol is unloaded. Remove the magazine. Then remove the two screws at the back of the slide, and pull the slide off to the front, exposing the recoil/firing pin spring.
Lift the spring and its guide up and disengage it from the its support on the frame. Push the spring and the attached breechblock directly to the rear. Note that the spring is supposed to be "kinked"; don't try to straighten it or cut off coils.
Further disassembly is NOT recommended.
To reassemble, hold the spring and its guide upward. Hold the trigger back and slide the breechblock into the frame. Pull the spring forward on its guide until the rear of the guide can be slipped down into the spring support.
Reinstall the slide and replace the two screws (long one to the front).
That's it.
