HK P30 Mainspring Question

[subaru1989]

I have a P30V3 in 9mm and am wondering what the stock mainspring weight is? And what factory parts can lower the trigger pull weight?

[P30]

From the factory, my P30 V3 contained the heavy firing pin block spring. I replaced it with the light one (#209296). This reduced the trigger pull weight by ca. 400 g (0.9 lb). I like the effect.

I measured these trigger pull weights:
- V2 LEM: before 3500 g = 7.7 lb; after 3060 g = 6.7 lb
- V3 SA: before 2470 g = 5.4 lb; after 2080 g = 4.6 lb
- V3 DA: after 4400 g = 9.7 lb

But don't replace the trigger return spring in the P30 V3. It's pretty hard to do and, as far as I know, for the V3 there is no better one than the original trigger return spring.

^^ This. It will reduce the trigger pull by 1 lb. The stock hammer spring is 214695 and I think it's 12 lbs.
