HK Mark 23 Pistols
The HK Mark 23 Caliber.45 ACP pistol gives shooters match grade accuracy equal to that of the finest custom made handguns—yet they exceed the most stringent operational requirements ever demanded of a combat handgun.

The Mark 23 provides this accuracy without the need for hand-fitted parts common in custom-built match pistols costing thousands of dollars more. One of the most thoroughly tested handguns in history, the MK23/Mark 23 project originated in 1991 when HK began development for the U.S. Special Operations Command, the unit that directs the activities of America’s mos elite military units, including the Navy SEALs and the Army Special Forces.

On May 1, 1996, the first MK 23 pistols were delivered to the U.S. Special Operations Command for operational deployment, making the MK 23 the first caliber .45 ACP pistol to enter U.S. military service since the venerable Government Model 1911A1.

PLEASE NOTE: When using Mark 23 pistols with a suppressor, fire only M1911 ball ammunition and use only Heckler & Koch approved suppressors as currently made by Knight Armament Company or Brügger & Thomet.

HK USP45 Tactical Pistol
An enhanced version of the USP45, the Tactical is designed for users who need the features found on the Mark 23, but in a smaller and more affordable pistol. The USP45 Tactical pistol approaches the precision found on the Mark 23 by adding an extended threaded barrel with rubber O-ring, adjustable trigger, and adjustable target-type sights to the USP45.

PLEASE NOTE: When using USP45 Tactical pistols with a suppressor, fire only M1911 ball ammunition and use only Heckler & Koch approved suppressors as currently made by Knight Armament Company or Brügger & Thomet.

HK USP Expert
Using the common lineage of the USP and developed in conjunction with internationally renowned target shooters, the USP Expert achieves the highest levels of accuracy by combining features of the Match, Tactical, and Mark 23 pistols with a new slide design. The result is a USP ideally suited to IPSC (International Practical Shooting Competition) and other practical target shooting applications.

A long target barrel with an O-ring seal optimizes accuracy. The O-ring is an innovative design feature found on the Mark 23, USP Match, and USP Tactical pistols—the tough rubber O-ring seals and centers the barrel in the slide until the barrel unlocks after firing. The O-ring increases accuracy, lasts more than 20,000 rounds, and can be quickly replaced without tools in seconds.

Other standard features include:

• Ambidextrous control levers located on both sides of the frame

• Long 190mm (7.5 inches) sight radius aids in aiming

• Patented HK USP recoil reduction system
• Match grade single-action and double-action trigger pull with adjustable trigger stop eliminates overtravel

• Low profile target sights with micrometer adjustment for windage and elevation

• Elongated target slide is milled from a single piece of high grade steel. The additional length aids the balance of the USP Expert during target shooting.
