MP9 won't fire in semi

I recently replaced some parts in the MP9 and reassembled.
It shoots fine in full auto, but semi is sketchy at best.
Looks like the trigger plunger(part # 13) isn't making contact with part #151 correctly.
What did I do wrong?
Any help would be nice.

It may be any number of different things. The fire selector itself, hammer sear, impact block assembly are areas that would also need looking at.
