After doing more measureing it looks like my dovetailed front sight is leaning too far to the right so the front and rear sights look skewed from each other and the windage is off.

I can't redo the dovetail so I'm going to replace the front sight with a band type so I can get everything lined up.

Should I use the front sight from a 1903 or from a 1903A3 Springfield?  It seems like a lot of early sporters used those front sights.  I think either one will be a perfect fit on my .643" diameter barrel but I don't know if one would be better than the other.
