Congrats on the purchase! It’s a great gun. I have a CZC Shadow 2 and run an 11lb hammer spring. It has a nice crisp trigger, but still around 7.5lb DA and 3.5lb SA. I also have plain Jane S2 with Cajun springs (11lb hammer as well), but stock hammer and mild polishing. The trigger is not as crisp, especially the reset, but the weight is much lighter. 6lb DA and 2ish SA. All that being said, I actually prefer the plain Jane gun with stock hammer and lighter but less crisp trigger. Is it all in my head? Probably, split times and accuracy are similar after the first DA shot. I second the idea to start with a Cajun spring kit if you want to tinker and go from there. They are solid firearms and I have not heard of very many if any warranty claims being submitted. Sent from my iPhone using Tapatalk
