I understand S&W is now producing the M&P 9MM with 1 - 10 twist barrels. This would the same twist rate Glock, CZ, FN, Tanfanglio and HK use in their 9MM guns. The 1 - 18.5 twist rate is really to slow to stabilize the 147 gr 9MM bullet.

From my experience my CZ's will shoot inside an inch at 15 yars using the Lyman 147 gr 9MM bullet. The same bullet of my MP using the same load won't hold 4".

I hope to be able to get a 1 - 10 barrel from S&W once they become available.
