Houston PD SWAT used them for a while in the early 2000s. The officer involved shootings they had with them demonstrated that they only worked to get fast stops if you dumped half a mag into the perp.
No Bueno.
They got rid of them and went to M-4 pattern carbines, 5.56 terminal effectiveness is quite good at urban ranges.
5.7x28 has about the same power as .22 Magnum, and has terminal effectiveness to match.
I see the P90 being used by like police and hostage rescue that may or may not be shooting through armor, but where overpenetration is always a risk.
