I love the x-compact grip far greater than the legacy P320 grip. It doesn't feel as fat and feels slightly more ergonomic, but no where near as ergonomic as the grip on the P30sk. I carry mine chambered in .357 sig, with a Gray Guns flat trigger.
I also have the P30sk and VP9sk. I think the sights on the X-compact are superior to the factory sights on the HKs, but that's subjective to the user.
