Twist rate used by AMU with 9mm 115 grain from Atlanta?

What twist rate did AMU use with 9mm 115 from Atlanta?   Thanks.

I believe they used the 1-32, and now the 1-18. No clue really though.

Chris is correct, spoke with KKM a couple of weeks ago.  Both USMC and the AMU have both twist rates in guns.  1-18 is currently being used by AMU according to KKM.

Thanks KC.  Helpful to have confirmation.  For ammo testing, I have separate KKM barrels in 1:18 and 1:32 fitted to an otherwise too heavy Range Officer.   

Finally have zeroed onto wife's need for a bullseye pistol that does not weigh more than 28 oz. (about 800 grams).  As a test, had her shoot a whole (90 round) match with a G34 MOS without
debilitating fatigue.  As we all know, "fitting" is far from one-size-fits-all.
