For what it's worth,
I really like my Glock 19 and my FN Five-Seven. Glock is the first pistol I ever shot, so I'm very comfortable with it.
But recently I've come to favor the Five Seven. I purchased it about 3 months ago after trying it against a USP 45 and a Sig 226. The FN felt lighter in my hand and I was able to hit targets with it faster, repeatedly with smaller groupings. Thing has almost no recoil, though the sights needed some tuning out of the box
Then again I've never had to fire a shot in anger in my life. All my experience is with range dummies and paper targets.
