FNH is a company I've had a long fascination with and is one of the worlds small arms manufacturers I feel is among the best in history. From design to quality of manufacturing, FNH has long been a gold standard in military firearms. With the new FN 509 Tactical, how does it stack up? The FNS/FNX series is one of the products FN has produced I've been less than enthusiastic about. It's not a bad gun by any means and the consistent quality is certainly there. But what do I think of the new 509 Tactical? I outfit my FN 509 Tactical with a Surefire X300 Ultra and Trijicon RMR.
