Went to the range tuesday and put another 50 rounds through my fnp 40. when cleaning it afterwards found some peaned over metal on the slide. ammo was just federal fmj. contacted fn customer service and their answer was this is normal ware. When I told them this hasn't happened to my hks,glocks,springfields or sw they had no comment. needless to say iam done buying fn products. thanks just needed to vent.
