I have a M&P15 - 223 but can't shoot it at my home ( my house ) range so I bought a
Just Right Carbine that takes my M&P F/S mags in 9mm and just recently
found a Ruger PC9 that takes my P89 Ruger mags they are both a blast
(no bun intended) to shoot if S&W made one I would buy it too. I also think
they are a good Home defense gun just MHO.
