Training Replica: FN509 Compact

The FN 509 Compact is the versatile "Goldilocks" of the 509 family. While the standard 509 is a duty-sized powerhouse, the Compact is designed specifically for deep concealment without sacrificing the "shootability" of a larger pistol. It is roughly the size of a Glock 26 but features a slightly longer grip that allows most users to get a full three-finger purchase, especially with the pinky-extension magazines.

Key Design Elements

• The "3-Mags-in-1" System: One of the Compact's best features is its adaptability. It usually ships with three different magazine setups:

  1. 12-Round Flush/Pinky Extender: For maximum concealment.

  2. 15-Round Extended: Provides a grip length identical to the FN 509 Midsize.

  3. 24-Round Tactical (Optional): Turns the compact into a high-capacity home defense tool.

• Low-Profile Optics Mounting System: The "MRD" and "Tactical" versions of the Compact feature FN�s industry-leading plate system. It allows for the direct mounting of over 10 different micro red dots while sitting low enough to co-witness with the factory iron sights.

• Aggressive Grip Texture: It uses a mix of "grenade-style" checkering and sharp pyramids. This ensures the gun stays locked in your hand even during rapid fire with a smaller frame.

• Ambidextrous Controls: Unlike many other compacts that require swapping parts, the 509 Compact comes with a dual-sided magazine release and dual-sided slide stop as standard.

The Three Main Variants

The 2026 Premium Option: FN 509 CC Edge

If you want the absolute highest performance in this size category, the CC Edge (Compact Compensated) is the 2025/2026 flagship:

• Tool-less Compensator: Features a quick-detach compensator that reduces muzzle flip by 25%. It can be removed for cleaning with a simple 90-degree twist�no tools or shims required.

• Gold TiN Barrel: Includes a high-lubricity Titanium Nitride-coated barrel for smoother cycling and distinctive "Edge" styling.

• Precision Trigger: Unlike the standard 509's hinged trigger, the CC Edge features a flat-faced trigger that breaks at a crisp 90-degree angle (approx. 5.6 lbs).
