The gun shoots to the left and it is not my trigger pull.
Can I heat the sight blade with a small tip and bend it a little? Yea, I don't think much of the idea either.
You are shooting from a very heavy and stable rest? It is possible to bend some front sights slightly to adjust windage, assuming you are not too far off. Usually the old half-moon type. It shouldn't need to be heated. You might also try different loads.
