I got it fixed
I took it to a gun shop and they probably did what you said. They kind of scolded me for f ing with it before I had soaked it in paint thinner to loosen up the cosmoline. They charged me $10 bucks but that was worth it for my piece of mind. Also, they want $200 to totally clean it out and test fire. I did the soak job then finally figured out how to take it apart and put it back together again.
