Hello all! I've had my FNX-9 for about 4 months and have put 300 rounds through it mostly compromised of range ammo and some federal hollow points. I've kept it clean and well lubed with RANDs CLP. I really like this pistol, the ergonomics are fantastic and I have yet to have any malfunctions of any sorts. My only concern is the amount of wear that is already showing underneath the rear rail especially on the right side of the polymer frame. It's hard to tell from the pictures but it's worn atleast .003" off. My main question is this amount of wear typical on polymer frame pistols? Or is this something I should contact FN about regarding the warranty? If somebody with experience with polymer frame pistols could take a look at the pictures I provided and give me some insight I would greatly appreciate it!
