got an FNX 40 awhile back and finally got some rounds through it. shot through 300 rounds. 200 remington, 50 PMC, 50 Armscor. Not one issue with anything. very accurate when i shot it right lol (have habbit of a jerk to the trigger when i start hitting successively aka getting cocky lol). Only negative i had was the safety lever rubbing my thumb, BUT i noticed before I got range time and went ahead and sanded it down to be flush with the grip. besides that it is awesome and i love it for my first official handgun (rest are my dads). now all i want to do is buy up a ton of ammo and keep shooting only problem is i just picked up an AR-15 so gotta get some time with her now. Tell me how your FNX 9, 40, 45s are. Oh for lube i use my usual 5w-30 and dang it never fails me.
