The first question would be, is how consistent the Barrels lock-up, into the Slide? Accuracy besides the condition of the bore itself, is the Barrel locking up in the same position within the Slide on each cycle.
How hard, or easy was it to fit the Barrel to the Pistol? Did you fit it yourself, or have it done?
Photos of the rear of the Barrel where it locks up in the Ejection Port, just 1/4" prior to the Slide locking up, and at lock-up may help.
