I put these on my 45 ,they are nice sights.I have a set on my FNS 9C, same part numbers. (FN-102...) https://www.trijicon.com/na_en/products/product2_hdns.php?mid=25 .
I like the yellow front sight (or stock white FN tritium front sight...), but some people like the orange front. They glow in the dark either way.
Probably the best sights available for the FN pistol line up. After a few rounds you'll figure out where you need to hold it at 25 yards.
