Need higher front sight for FNX 40

I’ve an FNX 40 I love. It’s been 100% reliable and groups well with all sorts of handloads, I cater to the 165. However, it shoots high. Always have and I’v just dealt with it using a low lollipop hold. But I’ve now made it my sole home/yard gun and Id really like to use the POI hold. I’ve used several online sight calculators and I need a 0.230” high front. The factory sight is 0.200”. I ordered a Dawson Precision but they only had an offering for the FNX 45 and no matter how much filing I did to the dovetail, I could not get it tapped it. Can you please recommend another brand to get me right. Thanks,
Thomis

I called FNH and they said they never have heard of the problem which is bs. They did not offer a solution. I can't take any off the top of the rear, its the two-dot rear.

No one else has had to install a higher front sight on an FNX pistol?
