The FN 545 Tactical is a full-size, striker-fired pistol chambered in .45 ACP intended for high-capacity large-bore carry, range work, and practical shooting. It pairs a 4.71-inch threaded, cold hammer-forged target steel barrel and an optic-ready, serrated slide with co-witness tritium night sights. The package includes two magazines and a multi-footprint MRD mounting system; a robust red-dot such as a Holosun 507C is a suitable optic option under $1,000 for this platform. Typical uses include duty/service applications and competition or precision work at the range.
