The HK Mark 23 is a .45ACP (11.23mm) semi-automatic pistol, designed and developed in the early 1990s by the German firm Heckler & Koch for use by armies elite units. It has been in service with the US Special Operation Command since 1996 and with the Polish Army special unit GROM since 1998.

The decocker is found on the left-hand side of the gun. It is also an ambitextrous handgun, with the safety switch being located on the upper part of the handgrip, just below the slide, on both side of the pistol frame. The magazine release button is situated behind the trigger, on the lower portion of the triggerguard. It features a 15-cm-long steel, threaded barrel, which has a durability rate of 35,000 rounds. It has a fiber-reinforced polymer frame and a machined steel slide. The pistol comes with a forward rail for tactical flashlight or laser pointer and a sound suppressor can be screwed on the threaded barrel tip.
