Question: Can I use .45 Super ammunition in my HK USP?
Answer: We have tested a factory stock HK USP with .45 Super ammunition with excellent results. However, to minimize wear it is recommended that the recoil springs be changed every 3,000 rounds.

Versatility and Power for .45 Autos
The .45 Super was originally the brainchild of Dean Grennell, longtime managing editor of Gun World magazine. His project started as an exploration of the limitations of the .45 ACP. Specifically the 45 ACP case. The idea was to boost the performance levels of the 45 ACP without overstressing the gun. He based the first versions of the .45 Super on .45 Winchester Magnum and .451 Detonics cases trimmed to .45 ACP length. These stronger cases allowed for greater levels of performance, but to realize their full potential, a stronger gun was called for. Grennell and Tom Ferguson, a regular columnist for Gun World, took this concept to the late Ace Hindman, a well-respected Texas gunsmith. Hindman developed a method of converting 1911-type .45 autos to safely handle the .45 Super cartridge, and perfected the ammunition. Today, his son, Garey, operates Ace Custom .45's, offering .45 Super conversions for existing .45 autos and complete gun packages.
Using brass cartridge cases manufactured to .45 Super dimensions, Triton is proud to offer a complete line of .45 Super ammunition. The .45 Super delivers more energy on target than any other defensive auto pistol cartridge. The .45 Super conversion is the ultimate choice for .45 ACP fans offering the flexibility of using both .45 Super ammunition and .45 ACP without swapping any parts.
Now available! Springfield Armory is now producing 1911 style autos in .45 Super.
The .45 Super conversions and Gunsmith Kit Conversion Kits are currently offered for the Colt 1911 style Browning Link System (Colt, Para-Ordnance, Springfield Armory, AMT, Auto-Ordnance, etc.) and the Smith & Wesson line of .45 Autos (5" & 4 1/4" models).

Sounds pretty cool, and it sounds like the USP45/F could handle without a problem. It says nothing of the compact, though.
