First my opinions come from full size 75 experiences, not the P01.
I agree with Most above, especially to shoot the heck out of it first.
I can't speak for "YOUR" preferences , but I believe the $$ for the recoil system would be better spent elsewhere, like hammer and springs AFTER you break it in and get acquainted with the pistol's feel OOB. The 13# hammer spring should fire all the standard US-made primers if accompanied with a little DIY polishing---others maybe not. The 15# spring will reliably fire most all with no other work.
