After looking at the trigger again, it looks like some one used a file on the piece of the trigger that engages the sear. It is rounded off so the sear just slides under the trigger. Now I know I need a trigger. Problem is, I do not want to get one by process of elimination. I would like to buy one trigger I know will drop right in. Yes. it has the 3 screws on the part under the safety. It also has a long screw that screws in just above where the sear engages. Under that screw is a spring. The only thing I can figure out is it holds tension on the trigger pin. I measured the action bolts and they are 4 1/2"
