HK Mark 23 .45 ACP 5.87″ Threaded Barrel | 81000078

The Heckler & Koch Mark 23 is a full-size .45 ACP pistol designed for match-grade accuracy and robust operational use. It features a cold hammer-forged threaded barrel, one-piece machined steel slide and a corrosion-resistant polymer frame intended for extended service life. For a protected red-dot solution under $1,000 that pairs well with the Mark 23, consider a Trijicon RMR (Type 2) or a Vortex Viper red dot; both offer durable housings and sight radii suitable for a full-size platform. Appropriate real-world applications include precision target shooting and duty/operational use where a durable, accurate service pistol is required.
