If you can't find an HK USP Match hammer spring, an 11lb spring from Lazy Wolf is a good substitute; the factory USP match spring weight is between 10 and 11lb, so erring on the side of caution and going 11 is 'safer'. The P30 uses the same spring part number as the USP so the springs are cross compatible.
It won't help with the grit in the trigger...but it makes the trigger a lot more manageable.
