The back blast is a bit much, but still works pretty well, super quiet because the slide doesn't go back as far.
They both shoot very well of course, the USP9SD was designed to shoot suppressed, the P7 was not, so the sights are better and the back blast from the round exiting the P7 is pretty bad, goes right in your eyes, so I wear ballistic lenese. The P7 is VERY QUIET, the only thing you hear is the slide going back, and it does not go back as far as the USP, so its not too lound. I will try to get some videos posted here in the next few weeks.Very nice. How does it compare to your USP 9SD?
