That is the type of trigger spring that I have . There is something else not just right. The trigger spring had a piece of shim stock up under it. I could figure out why it was there. So I left it out. every thing worked fine except the spring did not push the trigger forward again. It seems like of the v spring is inserted correctly the long leg part of it did not engage the proper notch on the trigger. So it did not push the trigger forward. I had to reassemble it several times before I understood why they had put the shim in there. It reaches into the notch the spring should go in to but can't reach. Now everything works correctly except the trigger does not return forward enough for the trigger link to catch the hammer. Then a few minutes later it works.
