Here's a question. I see that there are two new springs included in the kit. If i put both in or just one or the other, what will that do? In a video i saw, they put in the heavier trigger spring but stuck with the stock sear spring. What if i did both apex springs? Or both stock springs? I don't want sneeze on it light. I want to be able to slowly pull back without the trigger "skipping" or my finger shaking as i pull. What does a heavier trigger spring do for my trigger? And what does a heavier sear spring do?
