Yes the current S&W Sport has a 1/9 twist. For me that isn't a problem as the heaviest bullets I shoot are the 64g power points which will work in even 1/12 barrels. Long range shooters, 600-1000 yards, would want/need a faster twist for the heavy/long bullets. The long bullets either take up a lot of powder space and/or won't fit the magazine or both. So the 1/7 or 1/8 .223 barrels are niche driven in my view. The 1/9 is plenty adequate for a .223 AR for me- ymmv. I think it still has the 5r rifling-mine is at another location so I can't verify that at this moment.
