DOES NOT FUNCTION AS STRIKER FIRED PISTOL just another nothing special firearm I will stick with the FNH series Review by TJ
My initial thought was I had a defective firearm when I picked it up from my local RK store. On a normal striker fired pistol you get a hammer strike everytime you pull the trigger, the 509 IS NOT that way. Its more of a single action type firearm as you have to either have fired a round to pull the trigger and get another hammer strike or manually run the slide. I watched some of the 509 reviews and if you watch they are manually operating the slide to get a hammer strike when not live firing. So there is nothing wrong with my 509 just the disappointment in the false advertising and also a shame on Rural King for not allowing their sales people to remove trigger locks so that prospective buyers can tell what kind of trigger pull and grip feel there is to a firearm. This is my 3rd or 4th buy from RK that had I of had the chance to feel and pull the trigger I would not have bought. I know plenty of people that refuse to buy a firearm from RK due to this policy. FN makes a quality product I just don't think function and operation wise the 509 is anything special. (Posted on 7/19/2017)
Phenomenal Review by Sgt G
FN has outdone themselves yet again with the 509. A pistol that has what it takes to compete within the MHS with high marks. You can not go wrong with any FN firearm. (Posted on 6/28/2017)
