The usual recipe for accuracy in a 9mm bullseye pistol is to use a slow twist barrel with a 115 grain JHP bullet. If you want to shoot 147 grain bullets, a 1:10 twist barrel is the way to go, but it would be a special order item from KKM (their standard twist is 1:16).

Jarvis makes a very good barrel for Glock and for a little more they can fit it in house to your slide. If leading is the issue try less crimp with lead bullets or go up a 100th on the OD of the bullet to get you a better seal.
I assume the rifling is not trapezoidal.
125gn likes it hot for accuracy I run 125gn jfp over 5.0 CFE and they ring the x ring with my PPQ at 25 yards and my guess the gun can hold the the 9 ring at 50 yards no problem.
If I needed better than that I would try Atlanta Arms 115gn or 125gn and see which one worked better,
I never had luck with 9mm and lead.

glock with heavy bullets
Thanks for all the info guys! my head hurts! talked to kkm barrels and they seemed to think that there standard barrel would work with the 147 over 3.2 231. but now you all got me thinking going with the 1:10 twist. may have to change order.
