What I'm trying to emphasize, which _JD_ highlighted two post before your's, is that I believe they would maximize and somewhat standardize the modularity that we've all come to love from HK if they adopted the rear decocking button from the P30/P2000 (the other 21st century USPs as you just put it) onto the HK45 line.

P30 Series not sure what varient had the center decock wait I believe the P2000 series has a central decock button but, like I said not sure which varient had it, I'm a good ol fashioned 45 ACP guy myself.
Personally, I think the P30/P2000 de-cocker is the better set up for those wanting a DA/SA gun, however some left-handed persons may disagree.
Isn't getting a gun ready to go quickly more important? I'm a lefty and getting a P30L (should arrive today ). The decocker is difficult to get to even if I break my strong hand grip, but I figure that I only have to make safe and put away the pistol when I have more time on my hands. As long as the S is still HTF I've got other things to worry about. I'm no pro or competitive shooter though, so may be mistaken.
I'm also getting the forum gun, and may turn it into a decock only ambi lever so it's somewhat similar to the P30.
It's a preference, that's why HK has all the different versions for trigger groups.
Personally, I've never had an issue decocking my USP's. I carry in condition 1, locked, loaded, with the safety on, simply because it is the manual of arms I am used to, and if I feel like "cowboying up" and carrying one of my 1911's, it will function in the exact same way I expect it to.
Honestly, I've never had to fire a USP in anger, but I've been through many training courses and other "high anxiety" courses with it, and never once did I negligently decock it. If I ever did, big deal, it still goes bang when you pull the trigger, and you all practice in DA mode just in case, right?
