FN FNX sights

So I have a FNX40, like the gun hate the sights. It shoots too low for my liking and would like to bring the the POI up.
My questions are, what is the stock height of the rear sight? I thought I read it was .220 but now can't find any info on the rear dimensions.

I see Dawson Precision has a rear sight with a height of .220

Also found a Serigny rear sight at .230 height

My thought process is, if the stock rear sight is .220, then get the taller Serigny rear sight and adjust the difference with a shorter Dawson Precision F/O front sight.

I am using the sight picture #3 hold, and the gun still shoots low by about 3-4 inches.

Did you call FN USA and ask them?
