Well the FNP45 is a big one for a CCW. As much as I like mine It would be my last choice for a CCW. Big and heavy... The FNX line looks to be just right though.

I have always liked the CZ75. Felt great in hand but I never shot one. Nice grip and feels very solid. The EAA witness looks like a good alternative. Would be cool to be able to spend ~$250 and add a new round instead of dishing out for a whole new firearm. At least in the idea of a carry weapon. Switch it up when you get the feeling for more or less. There seems to be a slide, barrel, and mag combo out there for all of the most common calibers.
