I used the 10# usp spring from Wolf in mine. Works great so far after 1500 rounds. It feels just like my P30L with 11k rounds and the same cut to length hammer spring.
The below link will answer most of your questions. I can't think of a scenario where warranty would be an issue but the OEM spring can be put back in in 30 seconds if need be.Hey guys...I am totally new to this....just got my first pistol, a P2000SK V1 (DA/SA) and am looking to see if it is possible to lighten the trigger pull. Will the modification listed above affect both the DA & SA pulls or just the DA?
Is this something a HK dealer/gunsmith will do? What does this do the HK warranty?
