had the full size FN 509 which is essentially the same pistol. trigger was meh. ambi mag release annoying. mags expensive and questionable construction. striker breakage on the 509 is frequently reported. in my hands the pistol does absolutely nothing better than a glock 17/19/45, M&P or any other decent SFA. add to this garbage FN customer service and product support with now 4 different pistol platforms in less than a decade (FNP, FNX, FNS, 509)...what's not to like?
