FN 545 Tactical 45 ACP Pistol with Night Sights

FN 545 Tactical: Big Bore Capability Meets Modern Design

FN has reimagined the full-size 45 ACP pistol with the 545 Tactical, a purpose-built handgun that refuses to compromise on capacity, ergonomics, or versatility.

Capacity and Firepower

The 545 Tactical breaks the mold with an 18+1 round capacity in 45 ACP—a significant leap from traditional single-stack designs. This modern magazine capacity means more time on target and fewer reloads during extended shooting sessions.

Suppressor-Ready Design

The 4.71-inch barrel is threaded and target-crowned, ready to accept a suppressor without modification. This forward-thinking feature appeals to shooters who value hearing protection and reduced recoil impulse.

Optics Integration

The slide features an optic cut machined for rapid mounting of your favorite red dot sight. Four interchangeable mounting plates are included, ensuring compatibility with most modern optics. Co-witness tritium night sights provide a reliable backup aiming solution in any light condition.

Ergonomics and Controls

Borrowing proven ergonomics from the FN 509 platform, the 545 Tactical features:

• Ambidextrous slide stop lever and magazine release for both right and left-handed shooters
• Picatinny rail for mounting lights, lasers, or other accessories
• Two interchangeable backstraps to customize grip fit
• Loaded chamber indicator for quick status verification

Trigger and Reliability

The high-endurance striker system delivers a crisp, approximately 6-pound trigger pull—clean and predictable for precision shooting. The black PVD-coated steel slide and polymer frame provide durability and corrosion resistance.

What's Included

Each 545 Tactical ships with two magazines (15-round and 18-round), two backstraps, four optic mounting plates, a locking device, owners manual, and a zippered carrying case.

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