SHADOW SYSTEMS MR920 War Poet | 9mm | 4.5″ TB | Holosun 507C | SS-1075-H

The Shadow Systems MR920 War Poet is an optics-ready, striker-fired 9mm pistol built on a polymer frame and delivered with a factory-mounted Holosun 507C. It features a fluted, threaded 4.5″ barrel and ships with two 15-round magazines. This configuration is intended for range use and competition where an optics-ready compact with a threaded barrel is desirable.

For an optic recommendation under $1,000 that pairs well with this platform, a Holosun 507C (already factory-mounted on this example) is a practical choice that provides a robust footprint and multi-dot reticle options suitable for both competition and range training.
