FN 509 Compact MRD Optics-Ready Pistol – First Look

The smallest addition to the FN 509 line of pistols, the FN 509 Compact MRD, is an optics-ready compact pistol featuring the patented FN Low-Profile Optics-Mounting System.

The FN 509 Compact MRD is chambered in 9mm and is striker-fired. It features a 3.7-inch barrel and compact slide, and is available in both black and flat dark earth (FDE) finishes. The patented optics mounting system allows for a low-profile, direct mount through a carefully developed plate system that perfectly positions the optic so that the focal point allows for a low-profile mount and co-witness with the all-black iron sights that minimize interference with the optic.

The frame, reduced in overall size for concealability, features a MIL-STD 1913 Picatinny rail that accepts most compact pistol lights, improved controls to aid in manipulation, improved texturing on the two included backstraps for better recoil management, and a new flatter faced trigger allowing for more controllable trigger press and cleaner break.

Each pistol ships in a branded soft-sided, zippered case with FN Low-Profile Optics-Mounting System plate kit, one 12-round magazine with pinky extender and one 15-round magazine with grip sleeve or in an all 10-round magazine configuration for states with magazine capacity restrictions. The FN 509 Compact MRD also has the capability to accept all higher capacity FN 509 magazines with use of a sleeve.

Manufacturer’s suggested retail price of the FN 509 Compact MRD pistol is $799.00 and is available to purchase through authorized retailers.

Shooting 1,270 Yards with a 5.56 NATO AR-15 Rifle

Guns & Ammo Rifles & Optics Editor Tom Beckstrand pushes the limits of the 5.56 NATO cartridge in this segment of “Long Range Tech” for Guns & Ammo TV. Pairing a SIG Sauer MCX Virtus rifle loaded with Hornady 73-grain ELD-M ammunition, Beckstrand attempted to ring steel set at 1,270 yards, an incredible distance for any 5.56-chambered rifle and beyond the typical range for an AR-15.
