KTOG would be a better place to ask about rechambering ... I wouldn't do so, I'd just get the hottest 9x19 or .40s&w ammo I could.
magazine compatibility
might be more flexible if the magazines are the same dimensions as one of the offered types, you'd have to cut out and remount the magazine release button on the grip, which might or might not work with the USP's magazine release type (which I'm a huge fan of) ... or perhaps you could transplant a USP's mag release into the grip ... i know that the non-Glock grips can be swapped out for other non-Glock grips ... again, a question for KTOG, where the real experts are.

I have never shot mine of a bench. That's not what I got it for. I can hit 8" plates at 100 yards off hand with out much trouble. The sights are crude and the trigger pull is pretty terrible. I have never felt hampered by its accuracy but I tend to shoot it at 100 yards or less as I do with my other PCCs.
To be honest, shooting past 100 yards with any PCC never enters into my mind.
If the OP wants to shoot past 100 yards (or have pinpoint precision at 100y) then a sub2000 isn't for you, without heavy modification (again,
listen up, nice people at Tech Sights!) ... either adding better iron sights or mounting an optic in a way that may remove the ability to fold.
CoRoMo:
Probably, the front sight is also part of the locking system to keep the gun folded, so you'll lose
some function if you move it back.
If you
really want to mount a suppressor, you'd be better off mounting an optic as well, and maybe pinning the gun into the unfolded position somehow, as folding it with a mounted suppressor would be less than effective.
On the other hand, I remember an Oleg Volk picture of a SBR/Supressed sub2000 that was interesting from a while back ...
That's how to do it, as far as I'm concerned.
I went the other way with mine, I put on the compact fore-end, which makes the gun look a bit spindly when unfolded, but I wanted to make it smaller/lighter and was never going to use the mount on the bottom of the standard fore-end, nor was I about to put on a quad-rail to mount my cupholder to ... so I tossed the compact fore-end in the cart when I was ordering other goodies from the KT website.
