trouble shooting

I have not taken the sideplate off or anything other than pull off the grips. It still does it with the grips off. If I pull the trigger hard (yank it all the way to the rear of the trigger guard and hold it there) the hammer will fall all the way down. If I press the trigger normally, the hammer hangs up or falls in a jerky fashion. Gun is clean.
