Yes, I actually like the stock night sights a lot due to the U-notch but mine didn't come with them. This will be my first set of Trijicon HDs so it's kind of an experiment. Wished 10-8 made a sight for these guns.
The FN e-store only sells nights sights for the FNX-45, and when I called they said they don't offer factory night sights for the FNS series. I guess I'll go with Ameriglos or Trijicon HDs.
