You may find that the SP01 or Shadow 1 are just a better fit.
I have both the S1 and S2 and as much as I want to think I shoot my S2 better/faster. The data shows that I'm better with my S1.
If you're finding the same results, then switch and use the SP01 as your primary. If you're shooting CO, I'd suggest the Shadow version though, so that you can mill the slide more to lower the dot.
