FN America FN 509 Compact Tactical 9mm Pistol 4.32" Threaded Barrel - 24 Rd

Designed for shooters who want maximum capability in a minimal footprint, the FN 509 Compact Tactical delivers duty-grade performance in one of the most concealable tactical 9mm platforms available. Built by FN America, this compact striker-fired pistol is engineered for everyday carry, range versatility, and suppressed shooting—all without sacrificing reliability or modern features.

At its core is a 4.3-inch cold hammer-forged threaded barrel, giving shooters immediate compatibility with suppressors and muzzle devices while maintaining exceptional accuracy and durability. The suppressor-height night sights (1-dot front, 2-dot rear) ensure a clear sight picture even when running a can or in low-light environments, making this pistol ready for real-world defensive conditions.

The Flat Dark Earth finish across the slide and frame adds corrosion resistance and a rugged tactical appearance, while the lightweight polymer frame keeps total weight down to just 26.2 oz for comfortable all-day carry. Interchangeable backstraps allow shooters to tailor grip ergonomics for improved control and recoil management.

Equipped with FN’s Low-Profile Optics Mounting System (FNOPTICMOUNT), the 509 Compact Tactical supports a wide range of micro red dot optics, giving users a major advantage in speed and accuracy. A Picatinny rail further expands accessory compatibility for lights and lasers, enhancing its defensive versatility.
