The FN America 510 MRD Comp (brand part no. 66102129) is a striker-fired pistol chambered in 10mm, built with a 4.1-inch barrel, an optics-ready serrated slide, and an FDE finish for duty-grade carry or hunting use. It ships with two magazines for a 10+1 capacity, and the pistol relies on FN’s proven striker system with no external manual safety for a fast, consistent draw-to-shot. Fixed sights keep the profile snag-free while the optics-ready slide accepts a red dot for faster target acquisition.
