What you are doing (I do it also) would be better described not by saying that you raised your front sight (afterall, you still hold that front sight under your target same as always), but that you very much lowered your rear sight…
I don't think lowering the rear sight (relative to the front sight) is a "better" description. Its accurate, describing the relationship of the sights, relative to each other when I take the shot, but is not descriptive of what I do, to get there.
I physically raise the muzzle of the pistol, I don't lower the rear sight. And while raising the muzzle has the effect of lowering the rear sight, that is the effect of the action I am performing (raising the front sight), not me lowering the rear one. Perhaps this is an optical delusion, because I don't see me lowering the rear sight, it stays in place, relative to my eye. What I see is me raising the front sight (by raising the muzzle) so that it stands up above the top of the rear sight blade.
this is also called "standing proud in the notch", meaning it sticks up /stands out.
Some folks call it "Kentucky windage". I don't know what they call it in Kentucky (maybe just "windage" ) but in my part of the country where I grew up, the old timers called ALL aim corrections, up, down, left, right, were "Kentucky windage".
Physically moving the sight (via an adjustment screw or by drift) was NOT "Kentucky windage" it was a sight adjustment.
