Looking at the diagrams of the Walther PPK i have come to the conclusion that the trigger spring is probably broken. Could anyone tell me if my assessment of this problem is correct?

Note: If the trigger bar is manually pushed up to engage the cocking piece the hammer falls quite nicely.

I'm not a gunsmith, but if you fail to get an answer to your question sign up with the P38 forum. They have a PPK section. Good folks on that forum and very knowledgeable.

I've looked through the few diagrams that I have and can't tell what moves the trigger bar up to engage the cocking piece. I'd think that if it was only the trigger spring though, you'd notice a problem with the trigger too. I don't see a separate spring for the trigger bar though.

Is there a chance that there's some "gunk" blocking it's movement?

There are also a few very sharp Walther afficianados over at the WaltherForum.
