I have a safety model, but from what I can tell, the srs changes the firing pin lifter to improve pull. Without changing a disconnector, the static position of trigger on reset will be the same. You could add the RRK-2 to improve this. Again, I'm more familiar with the safety models. You could call CGW David is good at answering questions.
The decocker install kit is just a nice punch and a correctly sized slave pin to make things easier.
