" It shoots fine "
If it shoots fine ... don't "fix" it ! Shoot it or put it back in the safe and let the heir's worry with it .

I wonder if the barrel was canted just a bit so that it would shoot fine...you probably would undo the POA / POI and then be stuck with a gun that doesn't shoot fine...and here we go all over again.

Sometimes you just need to let well enough alone !
