Mark 23, GREEN .45 ACP, DA/SA, two 12rd magazines

The HK Mark 23 .45 ACP pistol in GREEN (also known as the MK23 or USSOCOM Mark 23) is a legendary full-size semi-automatic handgun engineered for elite performance. Developed in 1991 specifically for the U.S. Special Operations Command (USSOCOM), it was selected as the Offensive Handgun Weapon System for elite units like Navy SEALs and Army Special Forces. This iconic .45 ACP pistol delivers match-grade accuracy rivaling custom-built competition handguns costing thousands more—without any hand-fitted parts.

Key features include a threaded O-ring barrel with polygonal bore profile for exceptional precision and easy suppressor attachment (compatible with suppressors like the Knight's Armament model), a match-grade trigger, one-piece machined steel slide, corrosion-resistant blued finish, and a rugged fiber-reinforced polymer frame. It offers DA/SA operation with a frame-mounted decocking lever, ambidextrous safety, and the ability to carry "cocked and locked" in single-action mode.

Extensively tested for reliability, the Mark 23 exceeded grueling military requirements: endurance over 30,000 rounds of +P ammunition, average 6,000+ mean rounds between stoppages, and sub-1.5-inch groups at 25 meters (with many under 1 inch). Its oversized design, high-capacity 12-round magazines (or 10-round in some configurations), and proven durability make it a top choice for tactical, suppressor-ready applications, collectors, and enthusiasts seeking the ultimate in combat-proven .45 ACP firepower.

Whether you're searching for the HK Mark 23 pistol, SOCOM Mark 23, or the most accurate suppressed .45 handgun ever fielded by special operations, this beast combines unmatched precision, legendary reliability, and tactical versatility in one package.
