FN 309 MRD 9MM 3.8″ 16RD/20RD Optic Ready

The FN America 309 MRD is a compact, internal hammer-fired 9mm pistol designed to combine practical carry dimensions with high-capacity performance and modern optics capability. Featuring a 3.8-inch alloy steel barrel and single-action-only operation, the 309 MRD provides a distinctive alternative within the modern defensive pistol market.

The direct-mount optics-ready slide is compatible with DeltaPoint Pro and Shield RMS footprints, while the reduced slide resistance makes manipulation easier. A new grip texture, reversible magazine release, accessory rail, and drift-adjustable sights further enhance the pistol’s versatile configuration.

Benefits

• Compact High-Capacity Design — The 3.8-inch barrel and compact dimensions are paired with 16- and 20-round magazine options.
• Optics-Ready Configuration — The direct-mount optics-ready slide supports compatible red-dot optics without requiring an aftermarket mounting system.
• Easy Slide Manipulation — The slide is engineered with reduced resistance compared with the FN 509 Tactical, making it easier to operate.

Features

• Internal Hammer-Fired SAO System — The single-action-only operating system features an approximately 5-pound trigger pull.
• Direct-Mount Optics-Ready Slide — Compatible with DeltaPoint Pro and Shield RMS footprints for streamlined red-dot installation.
• Green Fiber-Optic Front Sight — The over-molded green fiber-optic front sight pairs with a rounded white-accent U-notch rear sight.
• Reversible Magazine Release — The reversible release provides greater flexibility for different shooting preferences.

Additional highlights include a recessed target-crowned barrel, 1:10 RH twist, new grip texture, accessory rail compatible with lights such as the Streamlight TLR-7, shared FN 509 dovetail dimensions, and multiple redundant internal safeties with no manual thumb safety.
