This Model D-100 uses an over/under two-barrel cluster with a tip-up, break-open action for loading. A serrated barrel-release latch provides positive control during opening. The internal alternating strike mechanism sequentially fires the upper and lower barrels, and the design runs double-action only with a hammerless profile and half-trigger-guard.
Rollmarks include “HI-STANDARD — DERRINGER” with HS logo, “.22 CAL. MOD. D-100,” and “HIGH STANDARD MFG. CORP. HAMDEN, CONN.
