This is one of the most over hyped rounds I have ever seen.
It is supposed to be near .223 performance - but is more like a .22 Hornet... And out of a pistol - you bleed so much energy your lucky to get that much out of it. Out of the P90 - your getting the performance. Out of the pistol - your better off with a good old .45.
I mean, if I went around saying I was an Emperor because some
moistened bint had lobbed a scimitar at me, people would put me away!
