FN FNX-45 Tactical 45 ACP 15+1 w/ Holosun 407C Red Dot Optic

The FN FNX-45 Tactical with Holosun 407C red dot optic delivers precision shooting capabilities in a full-size .45 ACP platform engineered for tactical applications. This optic-ready pistol combines FN's proven reliability with modern features that serious shooters demand.

What Makes This Different

The FNX-45 Tactical stands apart with its factory-threaded 5.3-inch barrel and optic-ready slide machined to accept micro red dots without adapter plates. While standard .45 ACP pistols typically hold 8-10 rounds, this model achieves a 15+1 capacity through its double-stack magazine design. The included Holosun 407C provides a 2 MOA red dot with 50,000-hour battery life and multiple reticle brightness settings.

Key Features

• Factory-threaded 5.3-inch cold hammer-forged barrel with 1/2x28 TPI threading
• 15+1 round capacity with double-stack magazines
• Holosun 407C red dot optic with 2 MOA dot and solar failsafe technology
• Ambidextrous controls including slide stop, magazine release, and manual safety
• MIL-STD-1913 Picatinny rail for tactical light/laser mounting
• Flat Dark Earth polymer frame with textured grip panels
• Serrated stainless steel slide with front and rear cocking serrations

The 5.3-inch barrel length provides excellent velocity retention for .45 ACP ammunition while maintaining manageable overall dimensions. Accuracy testing typically shows 2-3 inch groups at 25 yards with quality ammunition. The optic-ready slide eliminates the need for gunsmithing modifications, while the threaded barrel accepts standard suppressors and muzzle devices. Weather-resistant coating on all metal components ensures reliable function in adverse conditions.
