FN 509 MRD 9mm 4.5 Barrel 10-Rounds OR

FN 509 MRD Features Operation is double-action striker-fired with a trigger that breaks between 4.5 lb and 6 lb giving a consistent press from the first round to the last. The barrel is cut from machine gun-grade stainless steel with a 1:10 RH twist and a polished chamber and feed ramp so a broad range of defensive and practice loads feed cleanly. An external extractor and a loaded chamber visual indicator let a shooter confirm condition at a glance while aggressive slide serrations give positive purchase for press checks and malfunction clearing. For duty professionals working under stress that simple repeatable manual of arms matters more than any single feature. Added slide weight and length damp muzzle rise and stretch the sight radius to 6.3 in for a cleaner sight picture at distance. At 7.9 in long 5.56 in tall 1.35 in wide and 27 oz the pistol still fills the hand without becoming unwieldy and the enhanced frame texture holds that grip through wet cold or gloved conditions. Three interchangeable backstraps tune circumference to the individual shooter rather than forcing a fixed grip. For households or teams sharing one pistol that adjustability makes a single gun fit several hands comfortably. The 509 MRD ships as a complete kit: four MRD mounting plates two magazines with high-visibility low-friction followers an owner s manual a locking device and an FN case. A MIL-STD-1913 rail molded into the polymer frame accepts weapon lights and lasers for low-light work rounding out a pistol that can be built up rather than replaced. The MRD also sits in a series spanning Compact Midsize and Standard frames so a carry gun and a home gun can share the same controls. For shooters assembling a red dot setup in 9mm without aftermarket parts or gunsmithing this FN package is available for sale at ARMSAGORA.
