Ok, I went out yesterday and tried shooting my gun with the secondary safety screwed to the "safe" position. The gun fired! Is it possible that the breech plug may be too long in length? Do breech plugs come in different lengths? There was no crud in the threads to keep it fron screwing all the way in.
I did unscrew the secondary safety screw and try to adjust it, nothing changed. I'm calling knight later on and going to try and get this figured out.
