Ok so I've been going over this in my head and I'm pretty sure I have it correct but I want to make sure. My buddies P226 consistently groups to the left with multiple different shooters and I'm going to move the front sight a little for him. Since it shoots left I want to drift the front sight left as well correct?
Which way to move sight?

The rear sight offers a better surface for tapping to correct windage problems, especially if you're using a brass drift (punch) and a small hammer. A sight pusher becomes almost mandatory, with some sights that are really tight. Two of my three Sigs have sights that only a sight pusher will budge. Rod
I've had some issues making adjustments at the front.
My front sight got lose in its dovetail, moved a little, and I had to make a really large correction at the rear.
After centering the front sight again, I could almost center the rear, too.
Something about the front sight not being centered over the bore resulting in rear sight adjustments being correct for only a single distance?
I slept through geometry, but maybe someone can help?
If the rear sight is not adjustable, then you're sort of stuck.

And now to answer the question not asked: How much?
Determine the sight radius
Determine the range to target. If you measured the sight radius in inches,convert the range to inches.
Divide the sight radius into the range. Write that number down.
That is the distance to the target in "Sight Radius Units"
Proportional rules of geometry,thats how many times the sight correction will be multiplied on target.
Example:
Sight radius 5.4 in.
Range 25 yds,or,75 feet,or 900 inches.
Divide 5.4 into 900= 166.6667. We can call it 167.
Lets say its grouping 6 in left at 25 yds. You divide 6 in by 167. You get .0359
That is the sight correction you need. It would be real close to 1/32 in.
Whether you measure it with a loupe and a scale,a calipers,or a depth mic,
Its good to know, better than "Too much,(target)not enough(target),hit it harder"(target)
