FN 510 MRD | 10mm | 4.1″ Barrel | FDE | FN 66101380

The FN 510 MRD is a full-size, striker-fired 10mm pistol with a 4.1-inch hammer-forged, target-crowned barrel and an MRD-ready slide. The polymer frame in Flat Dark Earth provides a textured grip and a MIL-STD-1913 accessory rail for lights or other accessories. For an optic, the Holosun 507C pairs well with this platform and sits comfortably under $1000 while providing a durable, low-profile red-dot solution.

Applications: range target work for control with high-energy cartridges, and backcountry or field hunting where compact power and controllability are important.

This pistol blends a full-size chassis with an optic-ready slide and a balanced, ergonomic grip frame to help manage 10mm performance. The MRD-ready slide and included mounting plates reduce setup time for a red dot, and the hammer-forged crowned barrel supports consistent accuracy at typical pistol engagement distances.
