Ok some more info on the differant models that I was able to find.
Model #66047 is a FNP .45 with black finish and night sights.
Model #66048 is a FNP .45 with satinless finish and night sights.
Model #47579 is a FNP .45 with stainless fins and combat sights white dot.
Model #47576 is a FNP .45 with black finish and combat sights white dot.
Also it seems the ones with the nights sights where listed as a USG on the online dealers like Budsguns.
In addition to these there are the tactical models that come with the threaded barrel and mounting for a red dot sight. But if you have one of those you probroly know what you have LOL!
Just hope this info helps anyone who was where I was. Just a bummer to be shot down by their customer service like I was. Which inturn kind of took away from all the fun of getting a new gun. (which does not happen often). But now I am back to feeling those good new gun vibes, and I think the range is calling!
