Oh yes, it was so "screwed up" that it was stuck and when I tried to lock it, I kept unscrewing the entire bottom cap .. of course I eventually got it free, but that was not the issue. Now that I have taken it apart I understand more of what the other customer complaints about the firing button were saying. Out of the box, the button seems perfect, but when you adjust the contact, it also loosens the firing button, increases the throw, and it become very wobbly.
I believe I saw a thread on FT where someone sanded down the delrin around the contact, thereby increasing the clearance of the bottom contact when you press the fire button .. this way you don't have to unscrew the contact, and lengthen the throw to get this baby to fire. I do have a dremel, so I guess I can either sand down the delrin, or .... take it apart again and figure out something else, because I don't think that a stiffer spring is the remedy... but can't say for sure yet.
But thanks for the suggestions because until you said it, I didn't even think of adjusting the bottom contact, which works for now, but I would have to keep a constant eye on it to make sure it did not unscrew any further, and release the entire button. Part of playing on team cheap Mod means that you have to be resourceful, and handy.
