The slide is marked "IVER JOHNSON'S MIDDLESEX, N.J., U.S.A." on the left and "CAL .380" on the right, aligning with early Middlesex production. The compact size, 3-inch barrel, and all-steel build give it solid heft and balance for a pistol in this class.
Its single-action-only design with a Browning-type locked-breech, short-recoil system is a defining mechanical feature and is uncommon among .380 ACP pocket pistols of the era. A 1911-style barrel bushing and control layout—including a frame-mounted manual safety and a button magazine release in the 1911-pattern location—provide familiar handling.
Fixed iron sights consist of a ramped front blade and a square-notch rear. The slide carries rear vertical cocking serrations with a standard ejection port and no front serrations, supporting a clean, purposeful profile.
The pistol has an external spur hammer, checkered brown grip panels, and a lanyard loop at the lower rear of the grip frame. It was made in the United States during the late 1970s to early 1980s period.
