I'm sorry but none of that nicely staged commercial helps me to not think this thing is a POS.
I have fird the real ones and wasn't impressed and people I know in the groups all say they would take MP5s or HK53s long before the P90 if for no other reason than the fact that P90 magazine changes are awkward at best. My first time seeing one was in a weapons course at Ft. bragg and I was excited to shoot it and the instructor told me he would rather have a sledge hammer.
Also despit FN's 15+ year campeign to get that round to be the new standard, it is (according to Janes def weekly) doomed to be an exotic that gets replaced before it ever takes hold.
Nato round choice is driven by the US for better or for worse and the US crossed that thing off the list a long time ago.
