What's Included
- Herbert Schmidt Mod. 21S "Sierra Six" .22 WMR revolver
The Mod. 21S Sierra Six features a six-shot fluted cylinder and a 5.5-inch steel barrel chambered in .22 WMR, set up as a single-action-only revolver with an external hammer. The "SIERRA SIX" trade-name rollmark identifies it within the Sierra Six series.
Construction combines a steel barrel and steel cylinder with a matte black zinc-aluminium alloy frame and receiver. The cylinder wears a polished blued/black finish, and the revolver is fitted with two-piece hardwood grip panels in a plow-handle profile.
West German commercial proof marks and a "Made in West Germany" marking are present, alongside the HS shield/logo on the cylinder. A date code "86" adjacent to the proof mark indicates 1986 proofing, placing this example firmly in the 1980s production era.
Sight configuration includes a blade front and a simple rear sight. The right-side loading gate pairs with an ejector assembly that uses an exposed coil spring and an extended rod-style handle.
