The FN 510 MRD is a full-size, striker-fired 10mm pistol with a 4.1-inch barrel and an optics-ready slide offering multiple footprint compatibility. It pairs a target-crowned cold hammer-forged barrel with a precision-tuned trigger and enhanced grip ergonomics for controlled, repeatable performance. For a practical red-dot solution under $1,000, consider a Trijicon RMR mounted to the factory MRD footprint. Common applications include service-style everyday carry and range training or field use where a robust 10mm platform is desired.
