The FN 545 is a polymer frame striker-fired semi-automatic pistol manufactured by FN America, a division of FN Herstal. Based on the FN 509, It is chambered in .45 ACP featuring double-action operation and a Picatinny rail located forward of the trigger guard.
The 545 was released in 2023 alongside the FN 510 (chambered in 10mm Auto). [2]
The FN 545 is a striker-fired handgun with a stainless steel slide with ferritic nitrocarburizing finish and a polymer frame. Black and flat dark earth (FDE) colorings are available. Barrel length is 4.1 inches (100 mm) for the Standard Full Size (MRD) model & 4.71 inches (120 mm) for the Tactical model. The slide has serrations on both front and back, for easy slide manipulation. There is a full-sized grip, housing 15-round magazines; 10-round magazines are available for states with a high-capacity magazine ban.
The backstrap of the grip accepts interchangeable inserts; one arched and one flat. Instead of a manual safety, the 545 includes an integrated trigger safety (the articulated trigger type like the FN FNS) as part of its four passive safety systems: a striker block, a drop safety, a trigger disconnect and a trigger safety lever.

Magazine releases and slide locks are present on both side of the gun.
Several variants of the FN 545 have been made available: [4]
