HK Mark 23 .45 ACP 10+1 5.87" Threaded Barrel Pistol 81000080

The HK Mark 23 delivers the proven performance that made it the choice for U.S. Special Operations Command. This full-size .45 ACP pistol combines match-grade accuracy with the reliability demanded by military and law enforcement professionals worldwide.

What Makes This Different

Built on the same platform that passed SOCOM's rigorous testing protocol, the Mark 23 features a polygonal barrel that extends service life beyond conventional rifling while maintaining sub-2 MOA accuracy. The dual-action trigger system provides consistent performance in both single and double-action modes, while the polymer frame reduces weight without sacrificing durability. Unlike standard .45 ACP pistols, the Mark 23's oversized components handle +P ammunition without stress.

Key Features

• Threaded 5.87" barrel accepts suppressors and muzzle devices with standard 0.578x28 threads
• 10+1 capacity with steel magazines featuring witness holes for round count verification
• Ambidextrous safety/decocker and magazine release accommodate left and right-handed shooters
• Serrated steel slide with front and rear cocking serrations for positive grip in adverse conditions
• MIL-STD-1913 accessory rail accepts tactical lights and laser aiming devices
• Polymer frame construction reduces weight to 39.4 oz while maintaining structural integrity
• Fixed three-dot sights with tritium inserts for low-light target acquisition

Field testing demonstrates the Mark 23's ability to function reliably after exposure to sand, mud, and temperature extremes from -25°F to +160°F. The polygonal barrel design reduces fouling buildup and extends accuracy retention through extended firing schedules. Law enforcement agencies report consistent performance through qualification courses, while competitive shooters appreciate the crisp single-action trigger break at approximately 4.5 pounds.
