I really like the way my USP 45 works, but it's too large to carry. While the 2000SK fits my hand great, I don't like the controls, or lack of them. So is it possible to get a 2000SK that has the Var 1 lever on the left side with safety, & decock, w/o the rear decocker button. Is it even possible to assemble one with HK parts. To me that would be the ultimate carry gun. GARY N4KVE
