FN 509C Compact 9mm Pistol 10+1 3.7" Barrel Picatinny Rail

The FN 509C delivers striker-fired reliability in a compact frame optimized for concealed carry and duty use. This 9mm Luger pistol combines FN's military-proven engineering with features demanded by law enforcement and civilian shooters.

What Makes This Different

The 509C features a cold hammer-forged barrel and enhanced grip texturing that surpasses standard polymer pistols in durability and control. The interchangeable backstrap system allows precise fit customization, while the ambidextrous controls accommodate both right and left-handed shooters. Unlike many compact pistols, the 509C maintains a full-length Picatinny rail for tactical accessories.

Key Features

• 10+1 capacity 9mm Luger with flush-fit magazine design
• 3.70-inch cold hammer-forged steel barrel with recessed target crown
• Matte black serrated stainless steel slide reduces glare

Field performance centers on consistent accuracy and reliable cycling across ammunition weights from 115 to 147 grains. The trigger breaks cleanly at approximately 5.5 pounds with minimal overtravel. Weather-resistant finish and internal components handle moisture and debris exposure typical in duty and defensive scenarios. The compact dimensions conceal easily while maintaining shootability comparable to full-size service pistols.
