Do the fnx Tac sights fit the fnx 9 I called FN and they said let them know if it does.

FN cuts all the dove tails the same, so yes, they will fit. POI vs. POA will more than likely be off though.

Ditto that. Minor fitting may be necessary and also an adjustment in POA to center your POI.

They will physically fit, but the 9mm front sight is slightly taller than the .45's since the 9mm is flatter trajectory.
I would just order the Trijicon HD FN-102 in either orange or yellow and save yourself a huge headache.

The rear sights are the exact same on either gun.

When you install them use a proper sight pusher, don't beat on 'em with a hammer and punch.
