The H&K P2000 and USP Compact are near full-sized pistols, the P2000SK is therefore more a compact sized then subcompact, in my opinion. Though the sight radius is small the acurracy is very good considering its 3.27 in. barrel.
I took the P2000SK to a 4-day training in NV in which it performed on par to full-sized Glocks, M&Ps and Springfield XDs.
It's tough to go wrong with a H&K.
