What's Included
- High Standard DM-101 Double Derringer chambered in .22 WMR
The DM-101 uses an over/under twin-bore barrel unit with a break-open action secured by a top-mounted serrated latch. A double-action-only internal striker alternates between the barrels, delivering two shots of .22 WMR in sequence.
Dimensions are compact with a 3.5 in barrel, an overall length of about 5.125 in, and a weight of about 11 oz. Capacity is 2 rounds. The size and layout reflect the model’s micro profile.
Construction is robust, with a steel barrel assembly and a metal frame. It includes a half trigger-guard integral to the frame. Sighting is straightforward, with a small fixed front blade and a rear notch milled into the barrel/latch assembly.
Factory markings are clear: the right barrel flat reads "HIGH STANDARD INC. E. HARTFORD, CONN. U.S.A."; the left barrel flat reads "DERRINGER"; and the left frame/barrel block is marked ".22 MAGNUM CAL." The D-prefix serial marking on the left side of the hinge block denotes East Hartford, post-1975 production and aligns with the Third-Style Type 3C rollmark configuration.
