FN 545 MRD Comp | 45 ACP | FDE | 66-102138

The FN 545 MRD is a striker-fired, semi-automatic handgun configured for .45 ACP with an optic-ready slide and compensated muzzle. It is built around a polymer frame finished in Flat Dark Earth and ships with two 10‑round magazines. For a sighting solution under $1,000 that pairs well with this platform, consider a compact red-dot such as the Vortex Venom 3 MOA; it co-witnesses effectively and maintains a low-profile footprint.

This pistol is well suited to precision range practice and competition-style pistol matches where a controllable, optic-capable .45 ACP platform is desirable.

This FN 545 MRD configuration balances a duty-minded .45 ACP cartridge with modern features: an optics-capable slide, a compensator to aid follow-up shots, and ergonomics designed for consistent trigger control. The included magazines, mounting plates, and case make it range-ready out of the box while the FDE finish provides a subdued, purposeful appearance.
