The FN 510 MRD pistol in 10mm with a black finish and a 10-round magazine configuration (brand part no. 66101381) delivers full-power 10mm performance in a state-compliant magazine capacity, without giving up the platform’s optics-ready slide. 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. Among optics-ready 10mm semi-auto handguns, this 10-round 510 MRD configuration favors shooters who need a compliant magazine capacity in a classic black finish.
