I emailed Tisa a couple of months ago relating my desire for a steel framed commander to rechamber a 9mm to 9x23Win. Their reply was as follows, which is questionable since they replied Newlines vs Nowlin. Anyway, double-check as I do question this response ... and post your outcome so I may correct my info if this was in error.
The Carry 1911 by TISAS has a Wilson Newlines ramped barrel which is interchangeable with other series 70 9mm barrels with the same style of ramp.
While I do not know if we have a steel bobtail planned, we do still have an aluminum bobtail pistol which we will continue to import. Please see it linked below.
