I really liked my FNP45 Tactical but haven't tried the newer FNX series. Superficially you can hardly tell 'em apart. Sucks that you had such a bad experience with their CS department. I never needed service, my ran like a scalded cat. Eventually I traded it in on an HK USP45 Tactical since the LGS finally got one and it's the one I wanted in the first place.
Shame there's so few options for a real gun with a hammer. If anyone wants to call me OLD, now would be a good time!
