While cleaning my CSA VZ 58, i remove the extractor, but the firing pin won't drop out. It appear the firing pin developed a bit of a lip. I made a picture to demonstrate, the red is where the lip would be.

It's very close to being able to be pushed out, the lip is minor, if it is really there. Any ideas?
