I currently have a P2000 in 9mm and a P7 PSP 9mm. Both are fantastic pistols and I would recommend both.
I have posted quite a bit about the P2000 since I got mine. Look at my post (#5) on this thread:

...and it links to my threads on the P2000. Since I got the extended baseplates for my P2000 I have like it more and more, to the point that it is now rivaling my SIGs for favorite shooter.
I actually traded my USP 9mm for my P2000 (I had to come up with another $300 bucks or something like that) and that has been one of the best trades I have made in my firearms acquisitions. The P2000 is at least twice the shooter the USP is, at least for me. I could never really get used to that big-boxy USP grip and the high bore axis - as much as I liked the looks of that gun and really WANTED to love it. The slide is much smaller, lower and lighter on the P2000, and the grip gives you (or me at least) far better control over the gun (with the extended baseplates).
The P7 is nice. They are expensive though. The PSP's are really the only ones that are reasonably priced, but they rarely come up in the EE, and when they do they are snapped up right away at prices higher than what people paid for them. I bought mine from ArmsEast when they had them for $850 (or something like that... it might have been $850 including the second mag). I could easily sell it for $1,000 or more.
P7's are good, but they aren't magical super-guns or anything. I've shot various of them over the years and they are fun, but I don't think they are any more accurate than other accurate autopistols (SIGs, 1911s, etc.).

On the issue of the P30 and P30-L, I communicate with a guy in Norway who has a P30-L. He has had his for quite some time now. This is actually him on Youtube:

The P30 was designed for German police. The P30-L was a variant for Norweigan police (or miliatry, I can't remeber). Civillians can buy them there as well, and have been able to for some time. The P30-L is on the HK USA website now.. but it still seems like a total phantom in terms of the North American market. People have been talking about that gun on this board and similar ones in the US for eons. If and when they show I will probably buy one, but until that time I would focus on what you can actually get rather than descending into the waiting hell that Maurice is currently in. We all know first hand that waiting for firearms (parts, mags, ammo, gear) SUCKS!!! and sucks big time. I would also be intersted (more interested actually) in just a regular P30 if HK will make some barrels for the Canadian market. I think it would be a better handling gun (although it is extremely close is overall size, etc. to the P2000).
