The original didn't have a brace. The recent versions did, but they were dropped when the ATF flip-flopped. Braced pistols are currently legal, but I suspect they're holding off until this makes its way through the courts. No guarantee they'll ever make them again.
Old thread, but the only place I could find it outside of gunbroker, is sportsmans warehouse and they were braceless.
I went ahead and SBR's mine as I like to have vertical grips on rifles.
