Thanks, I was wondering if that was the case. hkparts.net only list one hammer spring (HKP-2598) on their site for the P2000 SK and they don't differentiate between DA/SA, or LEM. I will call tomorrow and ask.
I called HKparts.net and they only list one hammer spring for both versions of the P2000 SK. It looks like the V1 DA/SA and V2 LEM use the same hammer spring.You would have to compare part #'s but I would think the P2000sk hammer spring from a V3 DA/SA version would be lighter than the stock LEM version. That is typically how it is.
