FN's 500 series features a variety of pistol options which are suited for a variety of tasks and wide range of shooters. If you prefer pistols with a bit more knock-down power FN is proud to offer the 510 MRD.Chambered in the venerable 10mm Auto cartridge this pistol packs a serious punch while still being easy and comfortable to shoot.Its 4.1" barrel is cold hammer forged and includes a target crown for long term accuracy and the feed ramp and chamber are both polished to ensure reliable feeding.The steel slide is optics ready thanks to FN's Low Profile Optics Mounting System which is compatible with most of the popular micro red dot pistol optics on the market today.For additional aiming options a set of steel iron sights are also included which are tall enough to co-witness with most pistol mounted micro red dot optics.To ensure that you hit those targets you're aiming at FN includes a crisp target grade tuned trigger that breaks cleanly at around 6 pounds of pressure.Features / SpecsStriker Fired Semi-Auto PistolCaliber: 10mm Auto15 Rounds4.1" Cold Hammer Forged Stainless Steel BarrelPolished Feed Ramp and ChamberRecessed Target CrownTwist Rate: 1:16 RHSteel Slide with Aggressive Front and Rear SerrationsOptics Ready - FN Low-Profile Optics Mounting SystemCo Witness Height Steel Iron SightsPolymer Frame with Interchangeable BackstrapsAmbidextrous Slide StopLoaded Chamber IndicatorPicatinny Accessory RailPrecision Tuned TriggerOverall Length: 7.7"Height: 6"Width: 1.45"Weight: 31 ozColor: Black
