Go for the H&K USP .40! I have that weapon, and it is sweet! Just shot it yesterday at a friend's farm and had a great time. While I was there, he got out his Chinese SKS carbine. Man, what a blast to shoot! I'm going to get one at the next gun show here at the end of June. Can I count that towards NFPD?
That's what I've heard too.... I handled the 2340 at a gunshow recently, and it just didn't feel as good as the classic Sigs or even the H&K for that matter.
