What is happening is that the little button on the front of the sear bar is being pushed into the sear by the trigger lever, and the trigger is not retracting the trigger lever enough to let the button come out into firing position. This button is what the trigger lever pushes on to rotate the sear so that it will release the firing pin.

I suggest that you take the sideplate off and check the functioning of the trigger, trigger lever, and sear bar relationship. Sometimes the pin that holds the trigger lever in will rotate out of it's locked position and keep the trigger lever from rotating far enough to release the sear bar button. If something is keeping the trigger from returning to it's full forward position, the same thing can occur.

I have found that on some guns, when replacing the trigger lever or sear bar, that the small bevel on the side of tip of the trigger lever that presses on the sear bar button will have to be widened slightly or polished smoother so that the sear bar button will slip past it when the toggle closes.
