Compact mag would be shorter so wouldn't reach in a F/S USP pistol, assuming because it has a lower round capacity. The full size mag might fit in the Compact USP, but would hang out a little. Just guessing here, as I haven't seen both mags together.
If anyone has both pistols, this would be the time to chime in...

I cannot take the credit. As much as I like this site HKPro is a must for HK shooters. I scammed the table from an old post there. It gets posted a lot due to the frequency of mag compatability questions.
