This is an understatement.... since buying my VP9, I now have a P2000SK, P2000, P30, and a P30L all V1. I love the VP9 but found it to be a little big for EDC for me, thus the purchase of the P2000SK. I really love the SK and that was the impetus for me to buy the other HKs. If a P30SK came out, I'm not sure Id buy..... who am I fooling. Yeah I probably would.
Regarding sights, I like the Trijicon HDs, I have them on all of my HKs except for the P30L where I have the 10-8 Performance/Fiber optic set up.
