Pardini SP Trigger Adjustment

OK. It is not so easy as I imagined.

For two days I switched to mechanical trigger and after all I adjusted the trigger as I like (I thought so). Today during routine rapid fire training (the first training with new trigger) I could do only 3 or 4 "normal" series (of 18). "Normal" - I mean - I could reset the trigger five times (and five bullets left the barrel in time). I was totally disappointed. After every shot I had to move my finger back too far to reset the trigger (I think I had to completely release the trigger). Only then trigger bar / dis-connector took appropriate position. Never had such troubles with Feinwerkbau AW93 (as well as with Pardini SP1 electronic).

Don't forget - I am talking about rapid fire (8, 6 and 4 seconds).

Now, at home, I think I found the solution. Overall trigger pull (1st and 2nd stages) must be as short as possible (and save - of course). Maximum 0,75-1,00 mm first stage length (movement of the trigger shoe). Very short and crisp 2nd stage.

Following photo fully describes my solution.
Pull the trigger and hold. Cock the hammer (pull the slide backwards and let it glide forward).
What do you see is very short overlap between the trigger bar / dis-connector and sear ("corner to corner").
And today I tried to shoot with 1,5-2,00 mm overlap.  Huge difference. 2,5 mm finger's backwards movement to reset the trigger was too much for me. I will let you know If this solution works (at least for me).
