40 to 9 Conversion barrel shifts POI 5" right @ 25?

[narwhal]

Got a new barrel for my 40 compact, a KKM 40-9 conversion barrel to shoot in IDPA CCP division.

I shot groups with it at 25 yards to test function. While groups were OK( < 5" 10 shot groups) they were consistently centered about 5" to the right of the bullseye. 

I drifted the rear sight to the left about .07" with my sight pusher. My concern is that it makes the rear sight look pretty off center although it's still within the dovetail and doesn't protrude off the side of the slide or anything. I can just start to see the very slight edge of the striker block hole visible on the right side of the rear sight but it's definitely in no danger of popping out.

Is this an acceptable situation? Could the slide to barrel fit with the new barrel just be that much different than the factory barrel? Function was fine in the first 50 rounds.

Thanks, I was just asking if it is outside the realm of what considered normal to have to drift the sights that much, and if it might be indicative of some kind of problem.  Sounds like it isn't, so it should be ok.

Agreed, thinking if your groups are consistent. It's all good, Good luck
