I had to put this on the back burner until this past weekend. I removed the trigger housing and lubricating the pins, making sure to keep the hammer hooks and related parts clean and dry. I also lubricated the enire gun at the same time. Took out to the range and it worked fine from the bench. Shooting from the off-hand, I began to experience the exact same problem. What I have discovered is that, if I keep the trigger pulled rearward after the shot, as one would would do with good follow through while also not lowering the muzzle or lifting the head to check the shot for at least 1-2 seconds after firing...in
that scenario, I can feel that the trigger did not reset after releasing it. Sure enough, on the next shot, the trigger is dead. If, however, I make a conscious effort to get my finger off the trigger, the trigger will reset normally. I don't consider this operator error. I have owned this gun many years and competed with it many years, and I am only now having this issue.
Can you clarify something? Is the trigger not traveling back forward to release the trigger from the reset hook, or is the hammer not catching and following the bolt? That would be the first thing to determine to start diagnosing the problem.
After this weekend's testing, I'm pretty sure the trigger is not resetting.
It sounds like the disconnector is holding the hammer, instead of releasing it to the sear as it's supposed to, intermittently. Inspect the disconnector and hammer engagement surfaces, and consider re-installing the original disconnector spring, (or an OE type instead of the Wolff) Hitting it with Gun Scrubber and relubing properly might be all that it needs.
The disconnector/hammer hooks and surface do not look worn. (I interpret "worn" to mean rounded off.) Gun scrubber and re lubrication helped but did not resolve the issue.
Hammer spring doubles as trigger spring. Can you see the hammer spring through slot in side of HS housing? If so, the housing is upside down and that can cause problems with the disconnect. Also a weak hammer spring could cause problems w/disconnect.
Another thing that could cause problem is a bent or worn trigger pin binding the disconnect.

It is assembled correctly. No window in view.
Technically, the part you refer to as the "disconnect" is the Sear, P/N 5546024, the part you refer to as the "sear" is the Trigger, P/N 5546020, and specific area is the hammer engagement surface.
The Trigger, P/N 5546020, Sear, P/N 5546024 and Sear Pin, P/N 5013673 make up the Trigger Assembly, P/N 5546026.
Thank you for the part numbers. I'm seriously considering replacing all three to just to be sure I get the culprit.
you might want to make sure the safety lever is not bent. that part bends before it breaks and may cause this kind of problem.

Interesting statement. Nothing appears to be bent, however, I noticed that the safety is difficult to engage. Disengages easily, as one would expect, but requires more effort to engage. (Functions fine in all other respects.) I'm actually thinking about removing the safety altogether and test firing just to see.
