Advertised on Guns America as FNX-45 Tactical, says clearly on the slide FNP. And yes, he sent other pictures but I didn't zoom in enough to see if it said FNP or FNX, I was more looking at overal condition of the gun. I mean I am mad just because it's not what I thought I was buying, but are the differences different enough that I should take action, or should I let it go? I know I've seen some threads on the differences between FNP and FNX, but of course I couldn't find any now that I'm looking lol. Thoughts anybody?
