Twist rate for 9mm

Has anyone worked at barrel twist rate to improve accuracy of 9x19?
I was wondering 'cause I have never read any articles about a study of twist rates for handguns. They all seem to be somewhere if the 1:10 to 1:16, and I have often wondered if the twist rates had ever been "optimized."

Everything I have read says a 1:32 KKM barrel is the way to go with 115gr jacketed bullets.  NSK used to post to the old list a lot.  He has a wealth a knowledge on the 9mm.  Wish he would post here.

I have had several 9mms built using KKM Precision 1:32 twist barrels.  Each has been absolutely awesome.

Dewey,
I've seen your hardball load posted over in the other section.  Do you have a successful softball load with this barrel?

No, I don't have a softball load. The load I use doesn't seem that bad unless you shoot it a lot. It's no where near the snap of a Power Pistol load. If it seems hot, try going up on the recoil spring. 

Pistol powders are temperature sensitive. The powder charge needed in the early spring and fall would be excessive at Perry on a hot July day. 

I can tell you from experience that shooting the Beretta too much will lead to tendonitis and elbow pain much the same as 45 hardball loads. The key is moderation and enough recoil spring.
