Jonk,
You are discovering that a lighter trigger pull translates into less force/motion pulling the trigger clear of the half-cock notch. Once you reduce the normal pull you will almost certainly have to reshape the half-cock notch.
Generally, this area is not too hardened. You will have to reduce the height such that the sear completely misses the tumbler. If you don't you risk hitting the sear and shattering it. One way to determine how much to remove is to remove the sear spring which allows you to rotate the tumbler by hand once the sear releases. Then, see if the tumbler will hit the sear. If it does you can then gauge how much to reduce the height of the tumbler. Once you get it clear, then you will probably have to recreate the notch using a Dremel (thin) cut off disk.
It's pretty easy to do, but can make you nervous as you may have to take off a LOT of material to clear the sear. But don't worry. Unlike the full-cock notch, the half-cock does not affect the trigger pull. It only has to be deep enough to capture the sear and hold it there.
Good luck!!
