Adjusting windage on fixed sighted revolvers have always been turning the barrel, bending front sight blade, or breaking out the files. Sometimes if you are lucky you may find a load that shoots to your POA.
Better off not turning the barrel...that front lug neds to be alingned with the ejector rod to work right, and the old pinned barrels kind of resent being turned.
I personally cannnot stand a leaning front sight...just bugs he devil out of me...the front sight is what you really focus on, and if it leans you tend to straigten it up, so end up leaning the handgun.
IF you are dead sure you want 2.5" of windage dialed in, then this is my cure:
1. I cut a shim the exact profile of the front sight.
2. Will solder it to the propriate side of the front sight...if you made it a near perfect profile, will mate up well.
You've just created a too-wide front sight. Now you can file the sight blade for whatever windage you desire and not have it come up too thin at the end. A little cold blue, a bit of soldering black, and a small needle file to extend the grooving across the new section of sight face...looks fine.
Do ti right, and it won't be noticable until you examin it closely...and even then, it's a neater fix than bending the sight or turning the barrel in or out.
