HK Mark 23 SOCOM .45 ACP Pistol 5.87" Threaded Barrel - 12 Rd

The HK Mark 23 stands as one of the most rigorously tested and combat-proven handguns ever developed, delivering match-grade accuracy with true military-grade durability. Originally engineered in 1991 for U.S. Special Operations Command—including elite units such as Navy SEALs and Army Special Forces—the MK23 set a new benchmark for what a full-size .45 ACP pistol could achieve in both precision and reliability.

Unlike traditional custom-built match pistols that require hand-fitting, the Mark 23 achieves exceptional accuracy through precision manufacturing and cold hammer-forged engineering. It consistently meets—and exceeds—the most demanding operational standards ever applied to a combat handgun, including extreme endurance testing, suppressor compatibility, and long-term service life under harsh conditions.

Delivering the perfect balance between tactical performance and precision shooting, the Mark 23 features a threaded barrel for suppressor use, ambidextrous controls for versatile handling, and a rugged polymer frame designed for real-world operational environments. Whether used for duty, defense, or precision range shooting, this pistol remains a benchmark for reliability, power, and accuracy in the .45 ACP platform.
