Since i have notime to use my handgun built so sadly, i have to let it go to some good hands. FN 509 Mrd come with Holosun 407c. The gun has been shot less than 300rds. Its also upgraded Apex Trigger. Comes with 3 mags. I could throw in a good holster for free if the deal is great. Foursix9..8nine1..1foursix2..
