Description:
Guns Listing ID: 660197



The FN 545 is a full-size, striker-fired semi-automatic pistol from FN Herstal, designed as a modern duty and defensive handgun with high capacity and .45 ACP performance. It builds on the FN 509 platform, scaled up for the larger caliber and enhanced with optics-ready capability.

Caliber: .45 ACP
Action: Striker-fired
Barrel Length: 4.71 inches (cold hammer-forged stainless steel)
Overall Length: Approximately 8.3 inches
Height: ~6.3 inches
Width: ~1.45 inches
Weight: ~33 oz (unloaded)

The FN 545 features a polymer frame with a stainless steel slide finished in a durable black PVD coating for corrosion and wear resistance. The slide includes forward and rear serrations for positive manipulation.

Magazine Capacity:

15-round standard magazine
18-round extended magazine

One of its standout features is the optics-ready slide. FN’s Low-Profile Optics Mounting System allows direct mounting of a wide range of miniature red dot optics using adapter plates, maintaining a low sight height and co-witness capability with suppressor-height sights.

Sights: Suppressor-height steel night sights (tritium), designed to co-witness with optics.

Trigger: Striker-fired with a consistent pull, generally around 5.5–6.5 lbs, with a clean break and tactile reset.

Ergonomics & Controls:

Interchangeable backstraps for hand fit
Aggressive grip texture for control under recoil
Extended beavertail to reduce felt recoil and improve grip
Fully ambidextrous controls (slide stop and magazine release)
