GP 100 Front Sight

I have a blue GP 100 with a six inch barrel. I swapped the barrel for a stainless four inch barrel. It has the pinned front sight. My first range trip resulted in the bullet impact about five inches high. Where can I find a taller front sight?

Try Ruger!

Ruger replied they do not support any taller front sights for the GP 100.

did you check out the link above?
It looks tall

I have not. I have reached out to Hi Viz Sights because they are about 50 miles away from me and I can drive to their shop very easily. It looked like the other shop would want me to ship my complete revolver to them to replace the front sight.
