Unsurpassed 9mm handgun

I've owned firearms for over 60 years.  Many of those have been handguns.  I've carried in the military, in law enforcement, and as a private citizen.  Until now, I hadn't owned an FN.  Frankly, I ordered my first because of an unbelievable price for content.   I was just adding to my collection.  All of my weapons are used.  I don't believe in "show" guns.  The 509 Law Enforcement is, quite simply, the finest handling, most accurate, unstoppable, handgun I've EVER had the pleasure of firing.  It eats any ammo, in any combination, round after round after round.  How serious am I about this?  How much do I believe what I've written?  I JUST ORDERED ANOTHER ONE!
