Thank you everyone for your kind feedback and suggestions so far. I don't take for granted the wonderful assistance and advice given by those who have gone before me.
There is one very good youtube video that I thought describes the problem but in looking closely it's not my problem. In his case, he can move the disconnector to a certain point by pushing down on it an still pull the trigger, but the hammer doesn't release. In my case, when I push the disconnector all the way down, the trigger doesn't pull back at all.
In the video, through the side window there is a metal piece moving side to side when the disconnector is pushed and when the trigger is pulled (even if the safety is on). Mine doesn't do that...which is not exactly encouraging. That at least is a sign that something different here. The disconnector does move and pushes down, but in that small viewing window, pushing down the disconnector would cause some small little pin thing to protrude in the window. When pulling the trigger after, that small little pin thing disappears. But of course, in the video, that guy could at least pull and reset the trigger with the safety off. I can't. So at least I know my problem is not needing to file down the top of the disconnector as by simulating travel by pushing it down even to its limit, the trigger is not moving
Now, if something is gummed up, that would be the best case scenario.
