There is two principal places where it could have been stuck. The first is the
cylinder release bar itself, which is inside the lockwork, and the second is the
long centerpin of the extractor.
It easier to start with the centerpin of the extractor. If you remove the forward
sideplate screw, then open the cylinder, it can be slid forward, and the assembly
will come off the gun. If you don't want to take the extractor rod apart, then
you should carefully slosh it back and forth in the solvent. What you are trying to do
is create a washing effect down the middle of the extractor rod. Maybe put a rag in the
bottom of your soaking pan, so that you don't scratch the cylinder surface as you
work it back and forth. It won't hurt to let the cylinder assembly soak for several
days - intermittently working it back and forth.
The end of the centerpin should project through the bottom of the extractor star.
You can press it in, and then let it return under its spring pressure. You might
even do this while its sloshing back and forth in the solvent.
You can also get a can of Bore Scrubber, and let it flow down the length of the
center pin. This product is something like Freon, and it boils at room temperature,
creating a scrubbing action. Once all the gunk is disolved and washed out of the
centerpin hole, you can blow it air-dry. It doesn't need to be lubricated. You can
oil the outside surface of the extractor rod, then depress it and oil the outside
of the extractor rod shaft.
When you get done, the centerpin should work freely when pressing its bottom end,
as should the extractor rod itself. You want to make sure that the extractor lug
pin, in the lug under the barrel, is working free. Flood it with Bore Scrubber, then
a light drop of oil on one end or the other.
If, after a few days of drying, that center pin is sticky, then you need to take the
extractor apart. Its easy to do, but you need to be very careful, soas not to damage
it. I can tell you how to do that, if need be.
