interesting --but it is either going to go or fail on the mags -- with no 20-30rd mags its gonna flop.
having played around with a 9mm ar -- i can tell you it is fun to shoot and has reasonable enough power for close in compared to a pistol. no it ain't gonna out gun no .223/7.62x39/300BO ect-ect rifle class rounds.
i figure in the world today a PPC/ pistol powered carbine is a good thing to have as who knows what the ammo situation might end up being. i had much rather defend the homestead with a 9mm PPC than a pistol --and this thing can get head shots way-out there, far beyond anything possible with a pistol. hell i even scoped my 9mm ar-15 --and it does quite well!
the good thing about the 9mm is it is accurate and quiet from a 16" sounds like a .22 rimfire all most.
the taurus being a blow back and not having decent mags makes it look like a slow seller to me.
now a gas operated PPC with a big mag--that would be the ticket--
maybe if taurus cut that price to 1/2 i might take another more serious look--
