With FN's patented Low-Profile Optics Mounting System and unparalleled modularity of the FN 509 platform, the FN 509 Compact MRD joins the ranks packing a full-size punch in a compact, optics-ready package. The pistol is 9mm and striker-fired with 3.7-inch barrel, standard 12+1 capacity and the capability to accept all higher capacity FN 509 magazines. The patented FN Low-Profile Optics Mounting System accepts nearly all commercially available miniature red dot optics and features blackout iron sights that co-witness. The improved controls aid in manipulation, the new improved texturing on the two included backstraps provides better recoil management, and a new flatter faced trigger allows for more controllable trigger press and cleaner break.

Customer Comments & Questions
Customer Reviews
As soon as you take down the gun for the first time to clean, you'll realize why you paid that much for it. The barrel wall thickness is in a league of its own. Guns with double the price don't have that barrel. You can see the quality of the build and material with your own eyes. I fired a1000 rounds and the gun is really smooth now. Don't replace the trigger, it gets really smooth. I don't like those blacked out sights though. I immediately put a red dot sight on it and I realized why the put them. They don't distract you from the dot. Im still considering putting suppressor height night sights as a back up. I really like SOSS, they always have firearms that are not in the market & priced competitively. Grab them quickly, they disappear as soon as they're listed. SOSS is my single source for buying firearms.
