Hello guys,
Because reloading is forbidden in my country I have to shoot what I can buy for my USP40F. My problem is that the 170 grain FMJ ammo available here is too hot for IPSC shooting (power factor 185-190).
I'm thinking on to buy some extra power wolff springs to tame the recoil a little. What spring power do you guys recommend instead of the factory 12Lb springs?
