I have been seeing more and more about this FN Five Seven, i guess its claim to fame is the 20 round mags, low recoil (less then 9mm) and a few other things, but whats the hype with them? Gun is very expensive, hard to find ammo? I guess this post is geared to why should i or shouldnt I buy one? I have no real fire to buy one, just want to know more about why these are so crazed, and if these are really worth the high list price.
