Shadow 2 hammer spring and trigger job Qs

[YVK]

I was messing around with a heavier hammer spring in one of my Sh2 today, and it seems like, while predictably increasing the DA pull weight, it lowered the SA pull. I was thinking that the hammer is now under higher pressure so maybe it is pushed through forward more vigorously. Am I making it up?

 

---Side note: anybody here prefers how Shadow 2 cycles with a heavier mainspring? Subjectively it looks flatter although both targets (15 lbs spring gun and 11 lbs mainspring gun) looked about the same.

 

 

Second question: anyone has a link on trigger job for Shadow 2? I know there is a general link above but Shadow 2 sear is different from regular CZ75. Thnx.
