Design Principles

A Brief History: Why the Model HD Military Matters

Before diving into serial numbers, you must understand the context. In 1942, as the United States ramped up for war, the military faced a critical shortage of handguns. While Colt and S&W were struggling to produce enough M1911A1s in .45 ACP, the military also needed a reliable .22 LR pistol for marksmanship training.

Enter High Standard Manufacturing Company of New Haven, Connecticut. The company had already made a name for itself with the "Model B" and "Model HB." The military contracted High Standard to produce a rugged, reliable, and accurate .22 pistol. The result was the Model HD Military.

Between 1942 and 1946, High Standard produced approximately 140,000 Model HD Military pistols. These were used primarily by the U.S. Army Air Corps and the Navy for aerial gunnery training and basic pistol marksmanship. The "HD" stood for "Heavy Duty" or "Heavy Barrel," though some debate exists. Regardless, the pistol’s accuracy is legendary.
