The magazine thing was just a rumor I saw on HKPRO recently - I meant to mean "Rumor has it..." more than "Word has it...". Sorry about the confusion.
I'd heard the reason for delay was because of the magazines a few times previously, so it seems more likely that there is real truth to that. Seems logical that HK would want to make the magazines readily convertible back to the original capacity as well, with the very real possibility of the AWB sunsetting. They probably don't want to tool up for a completely different magazine that no one will want in a 18 months, if we have any luck.
That was the first time I'd heard about it using the USP's mags, though. Could be complete BS, for all I know. I can't seem to find the thread over at HKPRO now - I think it was in one of the compact P2000 threads, but I can only find the "big" thread there now - perhaps the multiple threads were deleted to clean up the board and keep it in one thread?
