FN 545 Tactical | .45 ACP | 4.71in | 66101385

The FN 545 Tactical is a full-size, optic-ready striker-fired pistol built on a polymer frame and designed around a 4.71-inch threaded steel barrel. It ships with MRD mounting plates, suppressor-height tritium night sights, ambidextrous controls, and two magazines. For an optic under $1,000 that pairs well with the MRD-cut slide, consider a Holosun 507C or a similar compact red dot compatible with multiple footprints.

Applications: competition shooting for large-bore divisions and suppressed/subsonic training where a threaded barrel and suppressor-height sights are beneficial.
