The FN 510 MRD pistol in 10mm with a black finish and two 15-round magazines (brand part no. 66101379) delivers full-power 10mm performance in a striker-fired, optics-ready platform built for duty and defense use. FN America builds the pistol with a 4.1-inch crowned barrel and a slide cut to mount most major red-dot optics directly. Extra backstraps ship in the box to dial in hand fit, along with a premium zippered case and four MRD mounting plates for different optic footprints.
