Get a Blackhawk CQC Serpa holster for the P2000 and file down the bottom of it to fit the SK. If you don't file it down the holster will extend the full length of the P2000, which isn't needed for the SK. It will still work out of the box, but you're wasting space.
I use this combo for carrying my P2000sk w/ a P2000 mag and X-grip when I don't really have the need for concealment. The paddle wasn't worth a damn, IMO. So I use the belt loop attachment.
