HK Mark 23 .45 ACP 12+1 5.87" Threaded Barrel Pistol - Black

The HK Mark 23 delivers the proven reliability and stopping power that made it the choice for elite military units worldwide. This full-size .45 ACP pistol combines German engineering precision with tactical versatility through its factory-threaded barrel and ambidextrous controls.

What Makes This Different

Unlike standard duty pistols, the Mark 23 features a cold hammer-forged barrel rated for sustained suppressor use and a reinforced polymer frame designed to withstand extreme conditions. The serrated steel slide provides positive grip manipulation even with wet hands, while the match-grade trigger system delivers consistent 4.5-pound pulls. This pistol passed rigorous military trials including 30,000-round endurance testing and exposure to salt water, sand, and temperature extremes.

Key Features

• Factory-threaded 5.87" barrel accepts suppressors and muzzle devices with 0.578x28 TPI threading
• 12+1 capacity with .45 ACP stopping power for maximum terminal effectiveness
• Ambidextrous safety and magazine release accommodate both left and right-handed shooters
• Serrated steel slide with anti-glare finish reduces reflection and improves grip purchase
• Reinforced polymer frame weighs 2.42 pounds loaded, balancing durability with portability
• Three-dot tritium night sights provide target acquisition in low-light conditions

Field performance demonstrates sub-2.5 MOA accuracy at 25 yards with quality ammunition, making this pistol suitable for precision applications beyond typical service use. The gas-delayed blowback system cycles reliably with both standard pressure and +P loads, while the polygonal rifling extends barrel life and improves velocity. Weather sealing protects internal components from moisture and debris during extended outdoor use.
