My goodness, it does not seem to matter what members tell the OP, because he is apparently convinced the barrel is not "clocked" correctly.

I have been shooting S&W revolvers for almost 50 years, and I have examined them every closely over that time.

Nothing is wrong with your front sight, its placement, the installation of the barrel, or anything else.

If that particular placement of the front sight results in a tight group where you want the holes to be, then you have it sighted in properly.

If you can't stand it, then sell it.

But, there is nothing wrong with it.

Just so you know, because of the way I hold a revolver, I ALWAYS have to adjust my rear sight over as a centered rear sight puts my nice tight group slightly left. That is because I am right handed and crank my hand around the grip to get better leverage on the trigger for DAO shooting.

I care not one bit that my sight is adjusted a little over. That is what it is there for.

Do I shoot fixed sight revolvers? Yes. I use "Kentucky windage!"
