I thought it was cancelled?
In any case, the Taurus carbine heavy, is if the mag-forward design and uses proprietary mags of standard (for a 9mm pistol). The only real benefit to the mag-forward design is the use of high-cap mags. They didn't even make it work with their 24/7 or PT92 mags!
So, even if it's well-built, it's still heavier and longer than a purpose-built 9mm carbine needs to be, and doesn't even have capacity to show for it.
