If I were you I would throw out the idea of the 5.7. I've never shot one, but from everything I've heard it's one of those rounds that doesn't really fix anything, and if you are going to use it for any kind of defense I would have to say, both from looking at ballistics and from everything I have heard, even a 9mm will outperform the 5.7. This round has one purpose, really-to penetrate armor. It is light and it is fast, but it is seriously lacking in the energy/stopping power department. Some of the ballistics I've seen have it listed as low as 282 ft/lbs of muzzle energy out of a ps90, which has a good amount more barrel that the five-seven. It's certainly an interesting weapon/cartridge, but I would venture to say that unless you plan on encountering armored targets (or you just want it for the cool factor, which I can totally understand) then a 9mm, .40, or .45 will be a much better real world round. The FN will certainly mess up any BG, but in a fight it is not as important to kill your assailant (much less so, actually) than it is to stop him/knock him down. Any of the aforementioned handgun cartridges will likely do this better than a 5.7, which could just as easily go right through the target.
