Not visual but here goes.
Removal of the recoil spring from the recoil spring guide is accomplished by
pulling the spring away from the end of the assembly and removing the spring
retaining clip. The simplest way is to put the end with a angle on it on a
table or workbench. Grip it with both hands, at the top, like a ball bat, push
down relieving the spring pressure on the retaining clip. The spring can then
be held in a compressed position by one hand while the retaining clip is
removed with the other hand.
These clips are one of three types.
The first one is very common on Chinese guns and is a stamped metal piece with
a raised dimple in the center and a groove on each side, making it figure eight
shaped. When you remove pressure from the clip, slightly spread the two
twisted wires inside the recoil spring and the clip will fall free from its
position on top of the spring.
The second type is a round machined steel piece with two notches on the side
opposite each other. When you remove the spring pressure from the retaining
clip and spread the two twisted wires inside the recoil spring the clip will
The third type uses a rod inside the spring instead to the twisted wire used in
the two methods above. Again the retaining piece is a machined steel part but
instead of two notches there is only one. The rod has a flange at the end with
a corresponding countersunk cut in the retaining piece. When the pressure is
removed from the retaining piece it will move down the rod about an 1/8" and
can be slid to the side. There is a flat place on the rod which allows the
retaining piece to slid to the side.
