The DM-101 uses an over/under two-shot break-open design with a top latch, keeping the profile slim and easy to manage. Its micro size and all-metal construction pair with two-piece black synthetic grip panels for a straightforward, durable package.
The concealed-hammer double-action-only system fires each barrel in sequence, offering a simple operating cycle. Chambered in .22 WMR, it provides a two-round capacity with a 3.5 inch steel barrel cluster.
Sighting is handled by a fixed blade front and a notch rear integral to the barrel and latch assembly, providing a clean, snag-resistant sight picture. The left side is marked "DERRINGER" and ".22 MAGNUM CAL.", while the right side is marked "HIGH STANDARD INC., E. HARTFORD, CONN. U.S.A."
Manufactured in the United States in 1980, this DM-101 reflects High Standard’s Hartford-era production, with clear factory markings and the characteristic DAO derringer configuration associated with the model.
