FN's 545 Tactical is the .45 ACP sibling of the 509 Tactical, and it brings genuinely high capacity to a cartridge that has historically been capacity-limited. It runs a 4.71-inch threaded barrel for suppressor use, an optics-ready slide using FN's Low Profile Optics Mounting System, suppressor-height night sights and fully ambidextrous controls.

FN builds these to duty standards, and the 545 inherits the 509's testing pedigree from the military trials that produced it. Finished in flat dark earth, it is a complete suppressor-host and home-defense package straight from the factory.
