The High Standard HDM is an American semi-automatic pistol equipped with an integral silencer. Based on the High Standard H-D pistol, it was adopted by the Office of Strategic Services (OSS) during World War II. Because of legal concerns during wartime, full-metal-jacketed .22 LR rounds were developed for this pistol.

HISTORY

William J. Donovan demonstrated the pistol to President Franklin D. Roosevelt inside the Oval Office. During World War II, the HDM was adopted for use by the OSS. It later was used by CIA agents and US special forces units in the Korean and Vietnam War and supposedly up to the Gulf War.

The High Standard HDM is a conventional blowback-operated semi-automatic pistol fitted with an integral silencer which decreases its report by more than 20 dB. This pistol design was originally delivered on January 20, 1944, and original contract models were blued with a parkerized (phosphate) finish on the silencer. Follow on models were completely Parkerized. Post World War II models produced for the CIA were also blued. The weapon has a frame-mounted safety lever on the left in a similar position to the M1911A1 and Browning Hi-Power. The front sight is a fixed blade with a square notch fixed rear sight.

This weapon uses a heel-mounted magazine release. The weapon is effective at short ranges when the low energy of the round fired is taken into account. The design is simple and typical of the period in which it was designed.

The HDM is still used by the Central Intelligence Agency, the United States Marine Corps with 10 HDMS in use with Force Recon, and the United States Army Special Forces. Formerly used by OSS agents and Lockheed U-2 pilots.

During the Vietnam War, the .22LR suppressed High Standard pistols were again used by both CIA operatives (including Air America pilots) and Special Forces members of the classified Studies and Observations Group, including the Navy SEALs and Army's Green Berets. The pistols were put to use during a variety of operations including long-range reconnaissance patrols, snatch missions, ambushes, and assassinations. They were one of a range of suppressed weapons deployed and found use assassinating enemy officers and Communist Chinese observers, during snatch raids to capture high-ranking prisoners and in shallow penetration raids into Laos and Cambodia. Perhaps the most high-value target killed by a High Standard pistol was a North Vietnamese People’s Minister of Mobilization, shot in a crowded Hanoi square — the operative who shot him escaped unheard and undetected.

During the war in Vietnam, the World War II-vintage pistols were joined by newly made pistols modified to use a new suppressor developed by Frankford Arsenal in 1967; however, these proved less efficient and more bulky than the original Bell Labs design. The suppressed High Standard HDM/S pistols remained in CIA and special force's inventories well into the 1990s and a number probably are still retained today.
