I have an FNP-45 which i was having the known problem of out of spec ammo making the magazine springs bind. I was apprehensive & skeptical sending into FN for service but i had no choice so i sent in my 3 magazines without the gun statting my problem. Within 10 days i got a post card in the mail saying they received my item and a week after that i got a box with 3 brand new 15 round magazines. So i'd just like to publicly say THANK YOU FN!
