When selecting a defensive pistol that balances proven power with modern modularity, look for a platform built specifically to accept optics and suppressors without compromise. That combination of heavy-hitting caliber and adaptability is increasingly important for duty, home defense, and competitive carry setups.

Optics-Ready Design and Mounting Flexibility

This model features FN’s patented Low-Profile Optics Mounting System that accepts adapter plates, enabling mounting of more than 10 different types of aftermarket optics. The pistol ships with four adapter plates, making it straightforward to switch between footprint standards without gunsmithing. Suppressor-height iron sights are included to co-witness with a red dot, and the slide cap incorporates bump wings to protect the rear sight when no optic is installed.

Why the optics system matters

Low-profile mounting retains a slim slide profile for holster compatibility while giving users the customization of modern reflex sights. The included plates and backup sights mean the pistol is ready for a wide range of optics right out of the case.
