Courtesy of HKPRO:
"What were the changes H&K made to USP over the years?"

1993: Original USP9 and .40.

1994: Reduced the slide weight by 1.1 oz.

1994-95: Change to a polygonal rifled barrel (Prior barrels were standard land and groove)

1994-95: Change trigger transfer bar.

1994-95: Change recoil guide rod to a "captured spring version".

1995: Change trigger mechanism.

1995-96: Add rubber spur to hammer.

1995-96: Change angle on slide lock.

2000: Add locking feature to hammer strut support.

2001: Converted captive recoil spring retainer from c-clip to machined end on USP Compacts.
