I have probably only fired about 150 rounds thru my FNX40 but I find it to be very accurate with a very good trigger. The only con I could pick would most likely be seen as a pro by some. That would be the fact that it is a hammer fired pistol with a safety/decocker and can be fired single or double action (too many options can lead to confusion under stress for some).
I purchased this pistol as a home defense weapon but I do use it occasionally as a sidearm while out in the woods. So I wasn't very picky when I bought my holster. But, I must say the Uncle Mikes Sidekick Ambidextrous #15 fits great and wears comfortably. It also holds an extra magazine.
