FN 545 Tactical 45 ACP Optic-Ready Pistol

FN 545 Tactical: Big Bore Precision Redefined

FN has set a new standard for .45 ACP performance with the 545 Tactical. This is not a compromise pistol—it's a purpose-built instrument for shooters who demand capacity, accuracy, and reliability in a full-size platform.

Capacity and Firepower

The 545 Tactical breaks the mold with an 18+1 round capacity in .45 ACP, giving you genuine tactical advantage without sacrificing the stopping power that makes this caliber legendary. Two magazines—one 15-round and one 18-round—ship with the pistol, ensuring flexibility for training and duty use.

Suppressor-Ready Design

The 4.71-inch threaded barrel is cut for standard suppressor mounts, allowing you to run this pistol quietly without sacrificing velocity or reliability. The barrel features a black target crown for precision and durability.

Optics Integration

The slide is machined with an MRD (Miniature Red Dot) optic cut and includes four interchangeable mounting plates. Mount your favorite red dot in minutes and achieve pinpoint accuracy on demand. Co-witness tritium night sights provide a backup aiming system and low-light capability.

Ergonomics and Control

Built on proven FN 509 Tactical ergonomics, the 545 features:

• Ambidextrous controls: Slide stop lever and magazine release work equally well for left and right-handed shooters
• Crisp trigger: Approximately 6-pound pull with a high-endurance striker
• Picatinny rail: Mount lights, lasers, or other accessories
• Loaded chamber indicator: Visual and tactile confirmation of chamber status
• Interchangeable backstraps: Two sizes included for custom fit

Build Quality

The Flat Dark Earth PVD-coated slide pairs with a durable polymer frame, creating a lightweight yet robust platform. Serrated slide serrations provide positive grip in any condition.

What's Included

The complete package includes two magazines, two interchangeable backstraps, four MRD mounting plates, owner's manual, locking device, and a zippered carrying case.

The FN 545 Tactical is what other big bore pistols aspire to be.
